Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a plant cultivation device equipped with a ventilation system for protecting plants from abnormally high temperatures.

[Prior Art] A ventilation system powered by solar cells has been developed for the purpose of lowering the temperature inside a car parked under the scorching sun.

In addition, in agricultural greenhouses, etc., to maintain a constant indoor temperature,
An automatic ventilation system powered by light line power is used.

[Problems to be Solved by the Invention] In today's living environment, which can be called the era of universal automobiles, there is a noticeable tendency to pay more attention to the interior decoration of private cars. One way to enjoy it is to bring in fresh plants such as flowers, but sometimes the inside of the car after people get off the train can be as large as 70%.
Since it is not rare for the temperature to rise above ℃, it can be said that the environment is quite poor for plants, at least during the summer or the period around it.

The present invention provides a plant cultivation device that can maintain an environment in which plants can grow even in places where the room temperature is abnormally high by ventilating only a very limited space around the plants. The purpose is to do.

[Means for Solving the Problems] In order to achieve the above object, the plant cultivation device according to the present invention includes (a) a pedestal on which a plant cultivation bed is placed, and (b) a pedestal mounted on the pedestal. , a cover body surrounding at least the periphery of the plant growth space; (c) an air blowing means for ventilating the interior space of the cover body; (d) a temperature measuring means for detecting the air temperature in the vicinity of the cultivation bed; (e) a plant cultivation device comprising: (e) actuating means for operating the blowing means when the temperature measuring means detects a temperature equal to or higher than a set level; and (f) cold wind inducing means for supplying cold air to the blowing means. The configuration was adopted.

[Operations and Effects of the Invention] The plant cultivation device having the above-mentioned configuration, when the temperature measuring means detects that the space temperature near the cultivation bed has risen to a temperature unsuitable for plant growth, automatically adjusts the temperature based on this temperature information. The actuating means actuates the blowing means.

The air blowing means sucks in the cold air supplied by the cold air induction means and blows it toward the inside of the cover body, thereby ventilating the growing space of the plants and cooling them to a temperature suitable for their growth. When the temperature detected by the temperature measuring means falls below a set level, the operation of the blowing means is stopped.

[Example] The configuration of the present invention will be specifically described below based on an example shown in the drawings.

Figures 1 to 3 show the case where the vehicle is placed in the cabin of a car.
This figure shows an embodiment of an apparatus according to the present invention for admiring flowers and the like, and its general structure consists of a pedestal 3 that is shaped like a flat box and has an inlet and an outlet for ventilation air on the side wall and the top, respectively. , the cultivation bed 1 and the cylindrical cover body 7 removably placed on the top of the pedestal 3, the solar cell 4 attached to the outer wall surface of the pedestal 3, and the air temperature in the vicinity of the cultivation bed 1 are detected. , an electric fan 6 installed in the pedestal 3 as a means of blowing air only when a temperature higher than a set level is detected.
The main component is a thermostat 5 which serves as a temperature measuring means and an operating means for supplying electric power to the thermostat 5.

In this embodiment, the cultivation bed 1 is configured such that the bot 1 is prepared as a cultivation bed exclusively for the device, and the plant A is planted therein using an appropriate medium such as a water-supplying sponge or vermiculite.

The top wall surface of the box-shaped pedestal 3 made of hard synthetic resin has a cultivation bed support hole 3A in the center for stably supporting the bottom of the cultivation bed 1, and a cultivation bed support hole 3A extending around the hole. A cold air outlet 3C is provided.

At least one side wall surface of the pedestal 3 placed on the rear package tray C of the automobile faces upward.

A solar panel 4 is installed at an angle, and a cold air introduction duct 8 is installed on one side wall as a cold air guide means.
A cold air intake port 3B is provided for connection to the cold air inlet 3B. The air inlet side end of the cold air introduction duct 8 faces the ventilation opening at the rear of the vehicle body, as shown in FIG.

An electric fan 6 is installed in the inner space of the pedestal 3 as shown in FIG. In this embodiment, it is fixed to the top wall of the gantry using a bracket 9, but it is also free to attach it to the bottom wall.

In this embodiment, the thermostat 5 is installed in the cold air outlet 3C, but the temperature of the air in the vicinity of the cultivation bed 1, that is, the inside of the pedestal 3, the internal space B of the cover body 7, or the outer periphery of the device Any location where it can be detected is sufficient.

The cover body 7 is made of transparent synthetic resin, has a cylindrical shape, a prismatic shape, or any other suitable shape, and has an open top surface.

The operation of the above embodiment will be explained with reference to FIG. 4, which is a diagram of a power supply circuit to the electric fan 6.

Of course, the interior of the vehicle is air-conditioned while the vehicle is running, so there is no problem as a growing environment for plants. However, as mentioned above, there is a possibility of reaching abnormally high temperatures during the summer and the seasons when the sun is strong.

If the vehicle interior temperature rises above a set level, for example 50° C., due to strong sunlight shining on the vehicle body, the electrical contacts of the thermostat 5 are closed.

Under such circumstances, the solar cell 4 is naturally operating, and the generated power is supplied to the electric fan 6 via the thermostat 5. The number of rotations increases in proportion to the intensity of sunlight.

As the electric fan 6 rotates, relatively low-temperature fresh outside air is sucked into the inner space of the mount 3 from the rear ventilation opening of the vehicle body through the cold air introduction duct 8, and then flows from the cold air outlet 3C to the cover body 7. The high temperature air in the space B is replaced with low temperature air.

The high-temperature air discharged into the vehicle interior from space B is discharged to the outside of the vehicle through a ventilation port or another outside air communication port provided in the vehicle body for air conditioning in the vehicle interior. Therefore, if you want to use this device while the vehicle is parked, you should be careful to switch the operating mode of the air conditioner to outside air introduction mode rather than inside air circulation mode when you get out of the car.

At the stage of designing a new automobile, assuming the use of this device, ventilators should be provided in advance in the rear package tray and the lower part of the trunk compartment, or by doing it yourself, vents should be created in the rear package tray and the lower part of the trunk compartment. If this were done, it would be more ideal as a method of introducing cold air for plant protection, and the cold air introduction duct 8 could be inserted into this rear package tray opening as shown by the broken line in Fig. 3, and installed at the bottom of the luggage compartment. By connecting to the ventilation port 20, outside air can be introduced from the lower part of the vehicle body, which is kept at the lowest temperature among all parts of the vehicle body.

Since the power source for operating this embodiment device is a solar battery, there is no need to rely on power lines or batteries, there is no operating expense for the device, and the device can be moved freely.

FIG. 5 shows an electric circuit for operating the device as a second embodiment. The difference from the circuit of the first embodiment is that a storage battery 10 for storing the power generated by the solar cell 4 is connected. By using this circuit, the device can function reliably even in conditions where sunlight is insufficient.

The device of the present invention can be installed above the instrument panel in front of the driver's seat or between the front and rear seats, and is not limited to the interior of a car; it can also be used, for example, for gardening on the balcony of a home when the user is away from home. It can also be usefully used.
