Description

The desk with air purifying function {The desk with air purification function}

The present invention relates to a desk having an air purification function, and more particularly, to a desk having a photocatalytic function and an ultraviolet ray function inside a leg constituting a desk, circulating the air around the desk, The present invention relates to a desk having sterilization and deodorization of air and also having an air purification function in which these photocatalytic means and ultraviolet means are embedded in the legs of a desk and a separate structure is unnecessary.

Generally, air purification refers to removal of fine dust contained in the surrounding air, or sterilization and deodorization. Such an air purification apparatus is installed separately and is installed indoors, which is disadvantageous in that it takes up a large volume and is expensive. It may be efficient to partially deodorize and clean the air around the desk in the case of a desk-based office space or a single-use office space. Because the office is where many people sit and work, there is a problem of poor air quality in places where ventilation is poor.

In view of this, Domestic Utility No. 449664 proposed a device for generating oxygen on the top plate of a desk, and Domestic Practical No. 432742 proposed a device for generating negative ions on the top plate of a desk.

However, these conventional techniques have disadvantages in that the structure of the top plate is complicated because oxygen is generated or negative ions are generated by providing a separate structure on the top plate of the desk. In addition, there is no function to inhibit or sterilize harmful bacteria, and there is no deodorizing function for removing odor, so there is a limit to purify indoor air.

Conventional patent publications No. 2003-0069626 and No. 952927 have been proposed for sterilization and deodorization. These conventional techniques are technologies for sterilizing ambient air by disposing photocatalyst means on the outer circumference of an ultraviolet lamp.

However, these conventional technologies have a disadvantage in that a photocatalyst means must be installed in a separate chamber or a light-transmitting tube, and thus, when applied to a desk, a separate installation space is occupied.

It is an object of the present invention to provide a photocatalytic function and an ultraviolet ray function inside a leg constituting a desk so that air around a desk is circulated to the inside of a leg, And the air surrounding the desk is sterilized and deodorized. Further, since the photocatalyst means and the ultraviolet means are embedded in the legs of the desk, no separate structure is required, thus providing a desk having an air purification function that minimizes the installation space .

To this end, the present invention is characterized in that a passageway extending vertically through both sides of the upper plate is formed; A pair of legs fitted in the passage are provided in a hollow shape and the opposite surface is provided with an inlet leading to the interior and an outlet directed toward the passage; Wherein a leg connecting pipe connecting the respective inlets between the legs is provided with a blowing means having a fan rotated by a motor; A plurality of photocatalytic plates are provided inside each of the legs; The cover, which is placed in the passage of the upper plate and disperses air into the room, is provided with an ultraviolet lamp that emits ultraviolet rays to the photocatalytic plate.

According to the present invention, since the photocatalytic means and the ultraviolet means are built in the legs constituting the desk, the space occupied by the means does not need to be provided on the desk, which is advantageous in that the desk is simplified, And the cost for the system is also reduced.

In addition, since the photocatalytic means is made long as the height of the leg of the desk, the contact area of the air is increased, so that the sterilization and deodorization of air due to the reaction of the photocatalytic means and ultraviolet rays are improved.

1 is a perspective view of a desk according to an embodiment of the present invention;
2 is an exploded perspective view of a desk leg according to an embodiment of the present invention.
3 is a cross-sectional view of a desk leg according to an embodiment of the present invention
4 is a plan view of a desk leg of an embodiment of the present invention

As shown in FIGS. 1 to 4, the desk of the embodiment of the present invention is manufactured by manufacturing the legs 20 on both sides of the rear side of the desk, preferably a hollow pipe, among the plurality of legs supporting the desk top 10, Photocatalytic means and ultraviolet means are built in the legs 20.

Each of the legs 20 is constituted by an outlet 22 having an open top, and an inlet 21 is perforated on the side surfaces corresponding to each other. And a hollow bridge connecting pipe 23 connecting the respective inlets 21 between the legs 20 is provided.

The legs 20 are provided with a diaphragm 30 for guiding the air flow so that the air flowing into the inlet 21 flows downward and then flows toward the upper outlet 22. The diaphragm 30 bisects the inner space of the leg 20 and is installed close to the inlet 21 so that the inlet 21 is narrower than the opposite side.

A plurality of photocatalytic plates 31 are provided on the diaphragm 30 opposite to the inlet 21. The ends of the photocatalytic plates 31 are in close contact with the inner circumferential surface of the legs 20, As shown in FIG.

The photocatalyst coated on the photocatalytic plate 31 is oxidized and reduced (chemical reaction) using light as an energy source to decompose various bacteria, odor, VOC (volatile organic compound) and harmful substances to make them harmless to the human body , And the main component is preferably titanium dioxide (TiO2). The above titanium dioxide has good acid resistance and alkali resistance, is harmless to human body, particularly resistant to dirt and bacteria, and serves as a catalyst for decomposing carbon-based contaminants through ultraviolet rays to convert them into carbon dioxide and water.

The upper plate 10 of the desk is provided with a passage 11 through which the outlet 22 of each leg 20 is inserted. A bracket 24 for supporting the bottom surface of the upper plate 10 is provided on an upper outer circumferential surface of the leg 20 to be screwed with the upper plate 10. An ultraviolet lamp 41 is installed on the bottom of the cover 40 covering the passage 11. The ultraviolet lamp 41 is embedded in the leg 20 by being inserted into the outlet 22. The cover (40) is constituted by a plurality of gills to guide the purified air toward the user through the cover (40).

The ultraviolet lamp 41 preferably has a wavelength band suitable for causing a photocatalytic reaction with respect to titanium dioxide. When titanium dioxide absorbs light having a wavelength of about 185 to 385 nm, electrons are excited to initiate the reaction. Since the titanium dioxide has a strong oxidizing power, the VOC (volatile organic compound) can be removed, and a malodorous or sterilizing effect is exhibited.

The leg connecting pipe 23 is provided with a blowing means 50 at an intermediate point thereof. The blowing means 50 is provided therein with a fan 52 rotated by a motor 51, The negative ion generator 53 is incorporated. Ions are collectively referred to as air energies with electrical properties floating in the air. They are classified into negative ions with negative current and positive ions with positive current. In general, positive ions are present in polluted air, and negative ions are distributed widely in clear natural air. The negative ion generator 53 abundantly produces natural pure anions called vitamins in the air.

When the motor 51 of the blowing means 50 provided in the middle of the leg connection pipe 23 is operated, the fan 52 rotates to introduce ambient air into the desk. Then, it is spread to both sides and is directed to the inlet 21 of each leg 20. At this time, negative ions are added by the negative ion generator 53 to the introduced air.

The air entering the respective legs 20 through the inlet 21 is directed to the opposite side of the rear diaphragm 30 which is directed downward by the diaphragm 30. When the ultraviolet lamp 41 suspended from the cover 40 is operated, the photocatalytic reaction of the photocatalyst 31 occurs in the air, To kill harmful bacteria and remove various odors.

Because the office is a place where a lot of people gather and work for a long time, if the ventilation is not properly done, the harmful bacteria may breed, and the smell of secretion from the body spreads in the air, and the quality of the indoor air is lowered.

The photocatalytic means and ultraviolet means of the embodiment of the present invention are effective in sterilizing harmful bacteria in the air and removing odors. And it contains the negative ions in the air, so it makes the room air pleasant.

In addition, since the photocatalyst means and the ultraviolet means are embedded in the legs 20 supporting the top plate 10 of the desk, no additional structure is required, and the volume of the desk is not increased.

Since the photocatalytic plate 31 is formed long along the longitudinal direction of the leg 20 and a plurality of the photocatalytic plates 31 are spaced equidistantly from the diaphragm 30, the contact time between the photocatalyst and the air can be maximized. Further, since the cover 40 is separated from the upper panel 10, it is convenient to replace the ultraviolet lamp 41 coupled to the bottom surface of the cover 40. Since the diaphragm 30 is slidably fitted in the leg 20 and the ends of the photocatalytic plate 31 are in close contact with the inner circumferential surface of the leg 20 to suppress the shaking, There is an advantage such as convenience.
