Description

Air purification device using plant cultivation

The present invention relates to an air purifying apparatus using plant cultivation, and more particularly, by inhaling water and air outside the plant cultivation frame through a self-suction pump and supplying the inside of the plant cultivation frame to increase the carbon dioxide concentration, and additionally, The photocatalyst coating part is provided inside the plant cultivation frame to decompose volatile organic compounds contained in the outside air by reacting with light from a light source, thereby activating photosynthesis of the plant to increase plant growth and to purify indoor air. The present invention relates to an air purification device using plant cultivation.

Recently, people spend more time indoors, such as homes or offices, but as air pollution deepens due to insufficient ventilation and increased sources of indoor pollutants, the demand for proper management of indoor air quality is increasing. In the case of outdoor, pollutants are diluted by natural wind or atmospheric circulation, while in the case of indoor, the concentration of pollutants is increasing as pollutants continue to accumulate due to lack of ventilation and cleaning in a closed space.

When measuring indoor air pollution levels in new apartments, formaldehyde doubles the industrial site threshold by two to ten times, and another carcinogenic volatile organic compound exceeds the industrial site standard by five to ten times. Home wallpaper, curtains, paints, insulation, non-combustibles, adhesives, etc. have volatile organic compounds that are harmful to the human body, which is known to cause respiratory diseases such as bronchitis, asthma and allergies.

In fact, the indoor pollutant measurement resulted in severe dust concentrations of carbon dioxide, nitrogen dioxide and volatile organic compounds, and sick house syndrome.

Carbon dioxide (CO ₂ ) concentration is an optimal indicator for measuring air pollution. If it is less than 450 ppm, it is a healthy ventilation management level. If it is less than 700 ppm, it is an indoor level without any health problems even if it stays for a long time. There is no damage, but there is a feeling of unpleasantness, and if it is less than 2000 ppm, most people who are sleepy are the level where the change of condition occurs, and below 3000 ppm, the level at which health damage begins, such as a person who feels stiff or headache. When more than 3000 ppm, symptoms such as headache, dizziness, etc., and the level of harm to health for a long time. However, the concentration of carbon dioxide in the room during bedtime is observed to be about 2000 ppm or more. For this reason, an air cleaner is used at home.

The volatile organic compound (VOC) refers to a hydrocarbon compound that volatilizes in the atmosphere to generate odor or ozone, and is a carcinogen that causes disorders in the nervous system through skin contact or respiratory inhalation. Benzene, formaldehyde, toluene, xylene, ethylene, styrene, acetaldehyde and the like are collectively referred to. In most cases, these volatile organic compounds cause odors even at low concentrations. The compounds themselves are directly harmful to the environment and the human body, or may participate in photochemical reactions in the atmosphere to generate secondary pollutants such as photochemical oxides.

Conventionally, in order to solve the problem of deterioration of indoor air quality caused by yellow dust, fine dust, volatile organic compounds (VOCs) and the like, it has been developed in the form of home appliances that rely only on air cleaners. In addition, air purification technology using plants has been attempted, but it is difficult to expect sufficient performance because it is being developed mainly for indoor garden and wall greening in terms of simple landscaping.

Korean Patent No. 10-0721809 discloses a configuration including a coco panel for controlling water supply time using a timer and supplying nutrients to a plant, a drain for draining water, and a light emitting part serving as sunlight It is also at the level of landscape.

Korean Patent No. 10-0989705 discloses a technical configuration including a water supply means for arranging flower pots vertically and supplying water to each flower pot. However, rather than using a plant to clean the air, it is also a simple use of plants in terms of landscaping.

The

photocatalyst coating unit

140, 240, the photocatalytic reaction occurs by the light irradiated from the lighting unit (110, 210) as follows, it is possible to remove the volatile organic compounds as shown in the following [Formula 1].

A catalyst is a substance that plays a role in changing the reaction rate or starting the reaction without changing itself in a chemical reaction. Photocatalyst is a kind of catalyst, which means that the catalytic action is generated by receiving light energy, that is, an action or reaction that promotes catalysis (oxidation, reduction) as light as an energy source. Reactive substances formed through the photocatalytic reaction are also applied to the water treatment field and induce decomposition of various bacteria, bacteria and organic contaminants. For example, when light (UV or visible light) is irradiated onto titanium dioxide (TiO ₂ ), holes from which electrons escape from the crystal surface react with water molecules to form hydroxy radicals having a very high oxidizing power.

3 is a view for explaining the photocatalytic reaction used in the present invention.

As shown in FIG. 3, the photocatalyst 300 included in the

photocatalytic coating parts

140 and 240 according to the present invention forms a hydroxy radical 301 when irradiated with light (UV or visible light), bacteria and viruses. And volatile organic compounds 302 are decomposed by reacting with the hydroxy radicals 301 (303), and carbon dioxide 304 and water 305 are formed as by-products. Carbon dioxide formed as a by-product can promote plant photosynthesis.

As shown in Figure 4, the frame 100 of the air purification apparatus according to the present invention is provided with an observation unit 400 having a transparent material on at least one side to check the plant cultivation state. In a fully controlled plant cultivation device, photosynthesis may be enabled at night through an artificial light source. However, when the

lighting unit

110, 210 is turned on at night, light pollution may occur to a person, and may cause insomnia.

Thus, at night, a blocking member (not shown) for blocking the light of the

lighting units

110 and 210 leaking out through the observation unit 400 is required. In addition, the blocking member may serve to block natural light flowing into the air purification device from the outside during the day, when limiting the photosynthesis of the plant during the day.

Figure 5a is an illustration of an embodiment of a blocking member according to the present invention.

As shown in FIG. 5A, the blocking member 500 according to the present invention includes an electrochromatic glass.

Electrochromic glass is a glass that can electrically control light transmittance, and adjusts light transmittance by absorbing light by changing from transparent to dark blue. Thus, there is a disadvantage that the electrochromic glass generates heat.

The

controllers

170 and 270 of the present invention may adjust transparent and opaque states by adjusting the amount of current delivered to the electrochromic glass.

By the way, the inside of the air purifying device having a plant cultivation and air purification ability according to the present invention must maintain a certain temperature for proper growth of the plant. Therefore, the heat generation of the electrochromic glass may help to maintain the temperature of the air purification device.

5b and 5c are diagrams illustrating another embodiment of the blocking member according to the present invention. 5b and 5c show a cross section of a blocking member according to another embodiment of the present invention.

As shown in FIG. 5B, the blocking member includes a first glass plate 501, a second glass plate 502, a motor 503, a pulley 504, and a blind film 505.

That is, the blocking member has a form in which a blind film is included between two glass plates.

The

controllers

170 and 270 of the present invention may control the motor 503 to control the opening and closing of the blind layer 505.

As shown in FIG. 5C, the blocking member further includes a mirror reflection film 506 attached to the glass plate inside the frame.

Accordingly, since the light of the

lighting units

110 and 210 is reflected back into the frame through the mirror reflection film 506, the blocking effect may be increased.

The present invention is not limited to the above-described embodiments, and the scope of application is not limited, and various modifications can be made without departing from the gist of the present invention as claimed in the claims.
