Abstract

PURPOSE:To contrive the cleaning of air in a room through the cultivation of a plant by a method wherein a plant culture device is provided with an air suction passage, culture soil is provided in the air suction passage to serve as a clean air supply outlet and an air suction fan is provided below the culture soil in communication with the interior of the room. CONSTITUTION:A plant culture device is provided with an air suction passage 9 culture soil 20 is provided in the air suction passage 9, to serve as a clean air supply outlet and an air suction fan 6 is provided below the culture soil 20 in communication with the interior of a room. Since the hair root of the plant or the culture soil is used as a part of the filter in an air cleaning device, the cleaning frequency of the filter becomes small and, since the hair root and the culture soil are always supplied with air resulting in an abundant supply of the oxygen required for the growth of the hair root, the plant growth is accelerated and, when fine particles in the air are attached to the culture soil, they are dissolved in the water to become a fertilizer. Moreover, when the plant which changes carbon dioxide into oxygen as it grows is used, the air itself is cleaned substantially.

Description

[Detailed description of the invention] Industrial applications TECHNICAL FIELD The present invention relates to an air purification device.

BACKGROUND ART A conventional air purifying device of this type has the following features, as shown in FIG.
A filter 2a was provided at the front suction port 2 of the box body 1, a fan 4 was rotated by a drive motor, and the air was discharged through the looper 6a of the discharge port 6.

Problems to be Solved by the Invention In such a conventional configuration, since a certain number of suspended particles are removed by the filter 2, the filter 2 quickly becomes clogged and is defenseless against fine particles such as odors.
Since the filter 2 is made of an inorganic material, it has to be cleaned each time, which is a hassle.

The present invention solves these problems and provides an indoor air purification device through the cultivation of plants.

Means for Solving the Problems In order to achieve the above-mentioned object, the air purifying device of the present invention provides an air intake path in a plant cultivation device, and uses the culture soil as an outlet for purification in this air intake path, as well as discharging the culture soil. An intake fan is installed at the bottom that communicates with the interior of the room.

Additionally, a photodetector is provided to drive the intake fan.

Function: The air purifying device of the present invention has the above-mentioned structure, grows hair roots of plants in the culture soil, and maintains humidity at all times.
Culture soil and hair roots are made by absorbing dust and odors and purifying them.

In addition, a light detection device is used to drive the intake fan when the room is bright, allowing air purification to be performed when plants are active due to light.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIG.

In the figure, reference numeral 6 denotes an intake fan, which is rotated by a drive device 7. A safety guard 8a is provided on the suction port 8 in front of the intake fan 6 to prevent danger. The air taken in through the safety guard 8a passes through the air chamber 9 and reaches the drainboard 1o. A water tray 11 is provided at the bottom of the drainboard 10, and water is collected therein.

A water suction pipe 12 faces the water, and water is discharged into the culture soil 20 via a water pipe 14 by rotation of a water pump 13.

When the ice pump 13 is not operating, the capillary tube feed core 16 is in contact with water and constantly retains water.

Glass receivers 16 and 18 support a glass at the top of the water tray 11. A roof 19 is fixed to the top of the glass receiver 18.

In the above configuration, as the intake fan 6 rotates, air in the chamber passes through the suction port 8, reaches the air chamber 9, and then reaches the drainboard 10. Cultivating soil (compost) is entwined with the hair roots of the plants on the top of the drainboard 10, but when it gets wet with water and fine particles in the air are absorbed, the hair roots of the plants take it in as fertilizer and the roots grow further. become. The air sucked in by the intake fan 6 is purified by adding culture soil 20, and the purified air is supplied indoors. Furthermore, since the culture soil 20 is periodically supplied with water by the pump 13, the flotation effect will not be degraded.

Furthermore, the purification device itself is difficult to notice and can provide a comfortable living space.

Figures 2 and 3 show other embodiments, and Figure 2 shows one in which the suction port 8 is provided on the outdoor side to purify the outdoor air through the cultivation soil 20 and supply clean air indoors. It is.

In Fig. 3, the intake fan 6 and water pump 13 are driven by the light detection unit 21 of the bay window 23 and the control circuit 22. When the room is bright or the room becomes bright, the light detection unit 21 is turned on. This ensures that the air in the room is clean.

In the above embodiment, the air purifying device is installed inside a bay window, but the configuration is not limited to this, and the air purifying device can be buried in a general wall or installed as a single unit in a room. This also achieves the effects of the present invention.

Effects of the Invention As is clear from the description of the embodiments, according to the present invention, hair roots of plants or cultured soil are used as the filter of the purification device, so the frequency of filter cleaning is reduced, and hair root culture is Since air is constantly supplied to the soil, there is plenty of oxygen necessary for the growth of hairy roots, which promotes growth. When fine particles in the air attach to the culture soil, they dissolve in water and become fertilizer, and depending on the plant, As plants grow, carbon dioxide in the room changes to oxygen, which has the effect of refreshing the air itself.
