DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water temperature control device for a hydroponic cultivation plant box having planting blinds provided at openings of windows and the like of general buildings and the like for shielding solar radiation.

[0002]

2. Description of the Related Art In general, solar radiation shielding devices such as blinds, louvers, screens, curtains, and the like are provided at openings such as windows of buildings for the purpose of preventing glare caused by solar radiation and reducing the penetration of solar radiation into a room. Is attached.

As another example of such a solar shading device, there is a planting blind in which a potted plant is placed in a window for viewing and cooling. This uses a houseplant that has many leaves,
It reflects incident solar radiation on the leaf surface and humidifies the room with moisture evaporating from the leaf surface by the energy of solar radiation heat, thereby allowing the potted plant to function as a planting blind.

[0004] Such planting blinds include, in addition to those that grow plants in soil put in pots or planters, etc., those that use hydroponics to grow plants in water placed in a hydroponic plant box. In the case of hydroponic cultivation, similarly to the case of cultivation in soil, a plant box is installed in a place where there is sunlight, such as near a window, to block sunlight.

[0005]

When a planting blind is formed with plants grown in hydroponics, when the hydroponic plant box is exposed to sunlight, the water temperature in the box rises.
Generally, when cultivating a plant by hydroponics, the upper limit of the temperature of the nutrient solution is about 35 ° C. If the temperature is higher than that, the growth of the plant is inhibited, and the health of the plant is impaired.

In the case of a hydroponic cultivation plant box, the water temperature inside the box may exceed 35 ° C., especially during the summertime, because not only the outside air temperature is high but also the sunshine is strong. For this reason, in order to grow plants in a healthy state, it is necessary to lower the water temperature. However, no device has been established as a device for water temperature control.

[0007] An object of the present invention is to solve the above-mentioned disadvantages of the prior art and, when planting blinds are formed by hydroponics, can prevent the water temperature in the hydroponic plant box from rising due to solar radiation. Another object of the present invention is to provide a water temperature control device for a hydroponic plant box with planting blinds, which has a simple running configuration and uses the drain water of an air conditioner normally installed indoors, and has a low running cost. .

[0008]

According to the present invention, in order to achieve the above object, first, an air conditioner equipped with a drain pipe is installed in the vicinity, and in a planting blind formed by plants grown in hydroponics, the drain is provided. A water supply pipe into which drain water flows from the pipe is opened in the hydroponic plant box, a water temperature thermostat is provided in the hydroponic plant box, and water is supplied to the hydroponic plant box by the water supply pipe with the output of the water temperature thermostat. The gist is that a control mechanism for controlling is provided in the drain pipe or the water supply pipe.

Second, an air conditioner provided with a drain pipe is installed above, and in a planting blind formed by plants grown in hydroponics, a water supply pipe branched from the drain pipe is opened in a hydroponic plant box. The gist is that a water temperature thermostat is provided in the hydroponic cultivation plant box, and an on-off valve that is operated by the output of the water temperature thermostat is provided in the drain pipe.

Third, an air conditioner provided with a drain pipe is installed below, and in a planting blind formed of plants grown by hydroponics, the drain pipe is connected to a drain tank disposed below a hydroponic plant box. A water temperature thermostat is provided in the hydroponic cultivation plant box, a pump operated by the output of the water temperature thermostat is installed in the drain tank, and another water supply pipe having one end opened in the drain tank through the pump is provided. The gist is that the end is opened in the hydroponic plant box.

Fourth, the drain tank is provided with a float switch for detecting when the water level falls below a predetermined value and stopping the pump.

[0012]

According to the present invention, cold drain water discharged from the air conditioner flows into the hydroponic cultivation plant box through the water supply pipe, thereby preventing an increase in water temperature due to solar radiation. In this case, since the water supply to the hydroponic plant box is controlled by the output from the water temperature thermostat installed in the hydroponic plant box, water is supplied only when the water temperature reaches the set temperature.

According to the second aspect of the present invention, in addition to the above operation, when the air conditioner is installed above the planting blind, the drain water can be guided to the hydroponic plant box by natural fall. The structure is simple, and when the water temperature detected by the water temperature thermostat reaches the set temperature, the on-off valve provided on the drain pipe closes and the drain water is introduced into the water supply pipe.

According to the third aspect of the present invention, in addition to the above operation, even when the air conditioner is installed below the planting blind, the drain water from the air conditioner is temporarily stored in the drain tank, and from there. Pumped to hydroponic plant box. Then, when the water temperature detected by the water temperature thermostat reaches the set temperature, the pump installed in the drain tank operates to introduce the drain water in the tank into the water supply pipe.

According to the present invention, when the water level in the drain tank drops below a certain value in addition to the above operation, the pump is automatically stopped by the output from the float switch. To prevent idle rotation.

Denotes overflow pipes each having one end opened to the hydroponic plant box 2 and the drain tank 12, and the other ends of the overflow pipes 10a and 10b are connected to a drain pipe 11.

Next, the operation will be described. Drain water from the air conditioner 5 is normally discharged to the outside from the drain pipe 11 via the drain pipe 6, the drain tank 12, and the overflow pipe 10b, and the pump 13 is stopped.

The solar radiation hits the planting blind 1, whereby the temperature of the water 3 in the hydroponic plant box 2 rises, and the water temperature detected by the water temperature thermostat 8 reaches a set temperature (for example, 35 ° C.). Then, the pump 13 is operated by the output from the water temperature thermostat 8, and the drain water stored in the drain tank 12 is pumped up to the water supply pipe 7 and supplied to the hydroponic plant box 2.

Thus, the hydroponic plant box 2
At the same time, the temperature rise of the water 3 in the inside is prevented, and at the same time, the drainage water having high oxygen concentration and high contact with the air is supplied to the plant 4, thereby promoting the growth of the plant 4.

With this water supply, the water level in the drain tank 12 decreases. When the water level falls below the set water level, the float switch 14 is turned on, and the pump 13 is automatically stopped by the output from the float switch 14.
