Description

Picture frame type air cleaner}

The present invention relates to a frame-type air purifier, and more particularly, to a frame-type air purifier having a germicidal effect by removing cigarette smoke and fine dust by sequentially passing through various filters while having an interior effect using a lighting frame. .

Conventional air cleaners generally employ either a filter method or an electrostatic precipitating method. The air purifier of the filter type is excellent in removing fine dust, but has a disadvantage in that it is poor in sterilization.

On the other hand, the electrostatic precipitating method has an excellent function of removing sterilization or odor, but has a disadvantage of damaging the human body when it is used for a long time due to the generation of by-products and residual ozone.

Moreover, both of them have limitations in sterilizing pathogenic Escherichia coli, Staphylococcus aureus and bacteria such as O-157 or bacteria.

In addition, the air cleaner is generally installed indoors, but does not take into account the decorative aspect at all, there is a disadvantage that does not match the expensive interior decoration.

Accordingly, the present invention is proposed to solve these conventional drawbacks, and an object of the present invention is to combine tobacco and decorative dust to remove cigarette smoke and fine dust by sequentially passing through various filters having an interior effect. And to provide a frame-type air cleaner having a sterilizing effect.

Furthermore, another object of the present invention is to provide a frame-type air cleaner having a structure capable of sharing a light source used for an illumination frame and a light source applied to a photocatalyst filter for sterilization.

Disclosed is a frame-type air purifier positioned correspondingly.

Preferably, the illumination frame unit is composed of a pair of transparent members and a photo film interposed therebetween, and is displayed by the light source of the photocatalyst filter.

Preferably, the secondary filter may be a HEPA-grade nonwoven filter or an electrostatic precipitating filter manufactured in a melt blown method.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is an exploded perspective view showing an air cleaner according to a first embodiment of the present invention.

As shown, the frame 100 is made of wood, metal or resin, and detachably attached to the case 10.

The rim portion of the frame 100 is formed with a slit 110 to allow air to enter, and preferably may be formed on all rim portions.

Immediately after the frame 100, the illumination frame unit 200 is coupled by a suitable coupling member, for example, a screw. The lighting frame unit 200 may include a front protective transparent member 210 such as acrylic, a light guide plate 230, and a photo film 220 and a light guide plate 230 interposed between the front protective transparent member 210 and the light guide plate 230. Cold cathode fluorescent lamp (CCFL; 250) is provided on one side.

At the rear end of the illumination frame unit 200, for example, a chlorine filter 300 is provided as a primary filter for removing large particles of dust.

At the rear of the chlorine filter 300, a secondary filter 400 for removing fine dust or tobacco smoke particles is installed. Preferably, as the secondary filter 400, an HEPA filter including an electrostatic precipitating filter or a nonwoven fabric may be used.

A plurality of photocatalyst filters 510, 520, and 530 are superposed on the rear end of the secondary filter 400 via a light source 550 such as an ultraviolet cold cathode fluorescent lamp to remove harmful substances.

In addition, the rear end of the photocatalyst filter 500 generates a negative pressure is introduced through the air inlet slit 110, passing through each of the filters (300, 400, 500) to discharge the purified air 600 Is installed.

Hereinafter, the operation of the frame type lighting apparatus according to the first embodiment will be described.

The air introduced through the air inlet slit 110 passes through the chlorine filter 300 to remove dust and foreign matter having a relatively large particle size. Of course, instead of chlorinated filters, other types of filters can be used to remove large dust.

The air from which the large particles are removed of dust passes through the secondary filter 400 to remove fine dust. That is, the fine particles are ionized at a high voltage and the ionized fine particles are removed by sticking to the electrostatic force.

According to the present invention, in order to reduce the electricity consumption, it is possible to use a HEPA filter instead of the electrostatic precipitating filter, in this case, instead of the conventional glass wool (glass wool) using a non-woven fabric manufactured in the melt brown (melt blown) method This can reduce environmental pollution.

In other words, the filter is basically made by winding the nonwoven fabric to closely adhere the nonwoven fabric through heat fusion, etc. The nonwoven fabric by the melt brown method can have a micro size. In other words, rather than making the non-woven fabric by the melt brown method, it is possible to eliminate the intermediate process by inserting the filter directly, eliminating the insertion of harmful additives by the intermediate process.

Tobacco smoke particles, fine dust, or removed air passes through the photocatalyst filter 500 to sterilize pathogenic Escherichia coli, bacterium such as Staphylococcus aureus or bacteria such as O-157 and bacteria, and remove various odors.

Photocatalyst is a compound word of light and catalyst. It refers to a semiconductor material that decomposes various bacteria and contaminants by promoting the catalytic reaction (chemical reaction; oxidation / reduction reaction) as an energy source.

The most widely used material as a photocatalyst is titanium dioxide (TiO₂). When the ultraviolet light emitted from the ultraviolet cold cathode fluorescent lamp 550 installed as shown in FIG. 1 is absorbed, electrons and holes are generated on the surface, and these active species (electron, electric field) ) Decomposes most harmful substances.

That is, hydroxyl radical (OH) generated by the reaction of the hydroxyl group (H ₂ O) with the hydroxyl group (H ₂ O) has a high oxidation and reduction potential. The ability to oxidize all target substances, such as sterilizing more than 99% of various pathogens and bacteria is very excellent.

Air thus treated and clean air is discharged to the outside by the air discharge fan (60).

On the other hand, by the illumination frame unit 200 coupled to the rear end directly to the frame 100, because it is simply seen as a picture frame from the outside, it can be well harmonized with other interiors in terms of decoration.

In particular, by appropriately designing the size and arrangement of each filter and the air exhaust fan can be applied to the wall-type or pendant type can have a more sure interior effect. For example, since the ultraviolet cold cathode fluorescent lamp 550 itself has a diameter of about 2 mm, the distance between the photocatalyst filters can be reduced, and the ultraviolet cold cathode fluorescent lamp 550 is appropriately bent to the entire filter. Ultraviolet rays can be projected uniformly.

2 is an exploded perspective view showing an air cleaner according to a second embodiment of the present invention.

Only a configuration having the same configuration as that of the first embodiment of FIG. 1 and differing from this will be described.

An opening 20 is formed at one side of the case 10, and preferably, an edge 30 of the opening 20 is formed between the frame 100 attached to the opening and the case 10 so as to form a gap through which clean air is discharged. ) Is tapered.

Each of the filters 300, 400, and 500 is accommodated in the case 20, arranged in a direction perpendicular to the illumination frame unit 200, and interposed between the photocatalyst filters 510, 520, and 530. The cold cathode fluorescent lamp 550 corresponds to the opening 20.

In addition, the illumination frame unit 200 is composed of a pair of transparent members (210, 230) and the photo film 220 interposed therebetween, from the ultraviolet cold cathode fluorescent lamp 550 of the photocatalyst filter 500 Light is projected to the illumination frame unit 200 through the opening 20.

Therefore, the illumination frame unit 200 can display the image of the photographic film 220 without a separate light source.

In addition, since the clean air that has finally passed through the photocatalyst filter 500 is discharged into the gap between the surface of the frame 100 and the case 10, the object looking at the lighting frame may feel fresh and clean air.

In the above described the preferred embodiment of the present invention, but various changes can be made at the level of those skilled in the art. Therefore, the scope of the present invention should not be limited to the above embodiments but should be defined by the claims and their equivalents described below.

As described above, the present invention has various advantages.

First, by applying various filters in order to remove fine particles and tobacco smoke particles, at the same time, by applying a photocatalyst filter, various bacteria, bacteria, and odors contained in the air can be effectively removed, and the interior of the place to be installed is harmonized. There is an advantage to achieve this.

In addition, by using a cold cathode fluorescent lamp as a light source of the illumination frame unit or the photocatalyst filter, the overall size can be significantly reduced, and the bending can be freely increased to increase the design margin.

In addition, by appropriately arranging, the light source of the photocatalyst filter can be used together as the light source of the illumination frame unit to reduce power consumption.
