[Background Art] Groundwater circulation structure of an energy-saving mushroom grower {Circulation Structure of Ground Water in Energy-saving Mushroom Cultivation Facilities Using Groundwater Heat}

The present invention relates to a groundwater circulation structure of an energy-saving mushroom grower, and more particularly, to a groundwater circulation structure of an energy-saving mushroom grower using groundwater heat, which minimizes energy costs for mushroom cultivation.

In general, mushroom cultivation should provide a suitable environment for mushroom development. Especially, it is necessary to maintain the cultivation temperature and humidity at a constant level. In particular, in order to prevent the environment outside the mushroom from affecting mushroom cultivation during the summer or winter season, And to create an environment to grow and develop mushrooms inside.

In other words, the mushroom is constructed in the form of an external blocking structure in order to minimize external influences such as light, temperature, oxygen, moisture, ventilation, competition with other life forms and the fresh air supply and temperature A system for maintenance and a system for providing moisture are constructed.

In constructing the structure of the mushroom grower equipped with such a system, there are generally provided guidelines for the standard design for the mushroom grower of mast / concrete for the purpose of insulating / blocking from the outside, And concrete structure, it takes a long construction period and requires more installation cost.

As a conventional technique, the technique of the public utility model 20-2012-0006602 as shown in Fig. 1 is known.

This prior art is related to an air conditioning apparatus for a mushroom grower using geothermal heat, and includes an air inlet pipe (10) which is horizontally buried in the ground to allow air to flow in from an air inlet (11) ); An air conditioning room 20 provided with a cooling / heating unit for further heating or cooling the outdoor air so as to have a temperature suitable for mushroom cultivation according to the temperature of the outdoor air, ; And a mushroom grower 30 to which the air in the air conditioning room is supplied.

In this prior art, the air inlet pipe 10 is buried in the underground of the mushroom grower 30 and the air is introduced into the air conditioning room 20 equipped with a cooling / heating unit, the temperature is adjusted in the air conditioning room, It is blown up from the sides of the grower and flows into the room.

Since fresh air from the outside is supplied to the mushroom grower, it flows into the air-conditioning room in a state where it has undergone some degree of heat exchange with the geothermal heat, that is, the temperature is controlled, so that the air- However, there is a problem in that the effect is not sufficient because a single pipe is formed only horizontally.

As another prior art, as shown in Fig. 2, the technique of "mushroom grower" disclosed in Japanese Patent Laid-Open No. 10-2010-0048672 is known. This prior art is provided with a floor consisting of a soil layer and a gravel layer, a loess wall which is stacked vertically on the edge of the floor by laminating loess blocks, and a shielding roof for sealing the upper opening of the loess loess wall inner space.

This prior art basically uses yellow clay as a wall to maintain the temperature and humidity inside the mushroom growers constantly, but it has a structure in which the yellow clay blocks are combined with each other to have a long construction period.

As another prior art, the technology of "all-weather mushroom grower using sunlight and geothermal heat" of the registered patent 10-1354454 is known.

In this prior art, a solar thermal system including a battery is installed on a roof, and a geothermal system including a heat pump is installed on one side to allow indoor cooling and indoor heating is possible. In a mushroom grower in which a cultivation vessel for growing mushrooms is installed in a multi-stage re-battle, electricity obtained from the solar cell board is stored in a battery and supplied to a plug formed in the re-battle, and is cultivated. And an electric power is supplied to the heater built in the bottom of the cultivating compartment.

This conventional technology enables cooling and heating of the inside of a mushroom grower. In the summer, the cooling system is operated by using the electricity stored from the solar panel, thereby enabling the temperature inside the mushroom grower to be lowered in summer, In winter, heating can be performed using a geothermal system equipped with a heat pump, and the temperature can be directly increased by directly heating the plant.

However, this prior art has a safety problem because it involves the danger of short-circuit due to troublesome work and moisture which are required to connect and connect the receptacle formed in the re-battle and the heater and the plug for each cultivation in order to supply electricity, Also, there is a disadvantage that installation cost is increased and maintenance is difficult.
