Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to an underground water supply apparatus using evaporation or rainwater,

The present invention relates to an underground irrigation system using evaporation or rainwater, and more particularly, to an irrigation system using an evaporation action or rainwater caused by a solar heat or a temperature difference, so that even a small amount of water resources can be irrigated at all times. The present invention relates to an underground irrigation system using evaporation or rainwater which can be conveniently used by being installed in close proximity to a desired site or a crop site as needed.

Recently, the need for automatic irrigation equipment that can be easily installed and used has been increasing, as the experiential agricultural activities of the citizens such as weekend farms are increasing. In addition, due to the aging of the rural area, There are a lot of cases such as the failure to grow or the plant to die.

Typical irrigation methods include hose irrigation to supply water using a hose, drip irrigation to make a small amount of water seep out by forming a nozzle or fine water outlet at the tip of a thin pipe connected to the hole by making a fine hole in a plastic pipe or a tube , A fountain watering water which is sprayed with water through a hollow tube, a watering watering water which is sprayed with water by a nozzle, a mist watering water which is made into fine water by a mist device, a watering water which supplies water to the watering hole, And underground irrigation to supply water directly to crop roots.

All irrigation methods except underground irrigation are watering method in the case of cultivating crops that supply water to the surface layer. Since water is not supplied directly to the roots, the consumption of water due to evaporation is increased and the use amount of agricultural water is increased. And it may become hard to grow crops. Especially, in the case of pollen, the use of the ground watering method makes the soil in the pollen easily harder, so that the probability of the water flowing down the pollen wall is much higher than the water penetrates the soil, There is a problem that sufficient supply of water is not provided to the root.

Therefore, in order to prevent the degradation of crops due to the hardening of the soil, an underground irrigation system may be used. In the conventional underground irrigation system, the water is absorbed from the bottom by the capillary water, There is a problem in that the bottom portion of the pot is soaked in water so that sufficient water can be absorbed in the root.

In addition, even in the case of landscaping water, since the soil is hardened in the dry season, it is often wetted with the soil of the skin layer even if it is exposed to a small amount of rain or water. On the contrary, when the proper amount of rain falls or water is given, There is a problem that crops and landscaping water frequently occur due to the flow through the underground waterway.

In this connection, in Korean Utility Model Registration No. 20-0395961 (Registered on Sep. 8, 2005), a technique relating to an automatic watering apparatus having a moisture sensing function is known.

According to Patent Document 1, there is provided a display means for measuring the water content of the soil in the pot and automatically displaying the water content when the water content is insufficient, and indicating the lack of irrigation water for storing in advance in the irrigation container, By making them universally available, it has made it possible to prevent accidents in advance.

In addition, in Korean Registered Utility Model No. 20-0414682 (registered on Apr. 17, 2006, hereinafter abbreviated as "Patent Document 2"), a constantly flowing water pressure by a controller directly connected to water faucet (faucet) BACKGROUND OF THE INVENTION [0002] Techniques relating to automatic irrigation systems that allow water to be supplied to a flower bed are known.

According to Patent Document 2, there is provided a control apparatus for controlling a flow rate of a liquid, comprising: a controller which is controlled by a valve directly connected to a water supply and controlled by a timer; a supply pipe which is fastened to a controller and extends to a flowerpot and a flower bed, Since clean water is always supplied to the pollen and flower bed including the dropper to guide the constant, the plant grows and grows, and a proper amount of purified water is supplied through the controller. Therefore, the number of the collected water is unnecessary, The water tank for collecting water and the pump for the constant flow are excluded so that the manufacturing cost is remarkably reduced.

However, in the conventional automatic irrigation system as described above, the problem of soil hardening still remains because the irrigation water is used in the case of Patent Document 1. Also, in the case of Patent Document 2, a large amount of water is evaporated There is a disadvantage in that efficient water supply can not be achieved and a large amount of water can not be consumed.
