Hereinafter, a chest of drawers according to the present invention will be described in detail with reference to the accompanying drawings.

Attached Figure 1 is an exploded perspective view of a drawer according to the present invention, Figure 2 is a perspective view of a state in which the upper plate is contained in the drawer according to the present invention, and Figure 3 is a perspective view of the open state in the drawer according to the present invention.

Referring to the drawings, the drawer according to the present invention is configured to include a drawer body 110, a partition plate 120 and a drawer 130.

The drawer body 110 is composed of a lower plate 111, both side plates 112, a rear plate 113 and an upper plate 114.

The lower plate 111 is a member for closing the lower portion of the drawer body, and a predetermined length assembly groove 111-1 is formed on both upper surfaces from the rear side to the front side. That is, the assembly groove 111-1 is formed on the upper surface of the lower plate, and has a predetermined length from the rear side to the front side.

The side plates 112 are members for closing both sides of the drawer body, and the lower end is slid into the assembly groove 111-1 to be forcibly assembled. That is, the front end of the side plate 112 is inserted into the rear side of the assembly groove 111-1, and then pushed forward to be assembled, and it is coupled in a force-fitting manner so that it can be coupled without nails or screws.

In addition, a plurality of fitting grooves 112-1 of a predetermined length from the front side to the rear side are formed on the inside of the both side plates 112 in the vertical direction. A partition plate 120 to be described later is coupled to the fitting hum.

The rear plate 113 is a member that ends the rear surface of the drawer body, and both ends are fixed to the rear ends of both side plates. The rear plate 113 may be formed in an area capable of closing the entire rear surface of the drawer body, and may be formed in an area capable of closing only a part of the rear surface.

The upper plate 114 is a member for closing the upper surface of the drawer body, and is rotatably coupled through the rear plate 113 and the hinge 140.

Here, a mirror 114-1 is attached to the inner surface of the upper plate of the drawer body.

Therefore, when the upper plate 114 of the drawer body is in the closed state, the upper surface of the drawer is closed as in FIG. 2, and when the upper plate 114 of the drawer body is in the open state, It performs the function of a mirror field through which the attached mirror 114-1 can be seen.

When the upper plate 114 of the drawer body is in a closed state, the bottom surface of the upper plate 114 is seated on the upper surfaces of both side plates 112. In addition, when the upper plate 114 of the drawer body is in an open state, the rear end of the upper plate 114 is seated on the upper surface of the rear plate 113.

Here, the rear plate 113 is preferably fixed to the rear of both side plates 112 at a predetermined distance from the top of both side plates 112 to the lower side, as shown in FIG. 4 by the above structure. There is an advantage that the upper plate 114 is inclined rearward with respect to the rear plate 113 so that the user can see the mirror at a comfortable angle.

The partition plate 120 is assembled by sliding into the fitting grooves 112-1 formed on both side plates of the drawer body, and the drawer 130 is accommodated between the partition plate 120 and the partition plate 120.

Here, the reason why the partition plate 120 is assembled in a sliding manner is that when the height of the drawer 130 is high, a space is secured in the drawer without installing any one partition plate 120 so that a drawer having a high height can be accommodated. I made it possible.

Here, the cabinet body 110 and the partition plate 120 are made of a wood material, and the drawer 130 is made of a synthetic resin material. Therefore, the cabinet body 110 and the partition plate 120 made of wood can create a natural and luxurious atmosphere, and cost can be reduced through the drawer 130 made of synthetic resin, thereby improving price competitiveness. .

Further, on the surface of the drawer 130, 4% by weight of a grass concentrate containing acetic acid, 8% by weight of a solubilizer, 3.5% by weight of hydrocolloid, 1.5% by weight of sodium oxide, and 2.5% by weight of polyaniline Wow, melamine cyanurate 4.5% by weight, pentaerythritol 4.5% by weight, melamine phosphate 4.5% by weight, dimethylpolysiloxane 2.5% by weight, Reineke salt 1.5% by weight, alkylbenzenesulfonate sodium 1.5% by weight, prostaglandin A coating solution composed of 4.5% by weight of (prostaglandin), 3.5% by weight of DBNPA (2,2-Dibromo-3-nitrilopropionamide), 1.5% by weight of illite powder, and the remaining polyethylene resin may be applied.

When the coating layer is formed by coating with a coating liquid in this way, antibacterial properties, water resistance, and flame retardancy can be secured on the surface of the drawer 130, thereby maintaining a long lifespan and suppressing the occurrence of harmful gases in the event of a fire.

At this time, acetic acid is bonded to the grass concentrate to decompose organic matter attached to the drawer surface so that the coating layer adheres well, and together with the grass concentrate, it contributes to odor removal.

In addition, the solubilizer prevents layer separation and induces emulsion stabilization by implementing emulsification and solubilization properties of the compositions constituting the coating liquid.

In addition, hydrocolloid is added to form a gel and maintain a wet state, thereby determining adhesion for a long time and strengthening binding properties. In particular, it is added to enhance the waterproof function so that wettability does not occur.

In addition, sodium oxide is added to increase the tensile strength as an alkaline oxide, and polyaniline is added as a conductive polymer to reduce the electrical resistance of the surface to suppress the generation of static electricity.

In addition, melamine cyanurate has good resin dispersibility and improves flame retardancy and has excellent moldability without deteriorating the properties of the target resin. Pentaerythritol is a material that has intermediate properties between synthetic rubber and plastic. It is added to increase ignition resistance by preventing and inducing an increase in the limiting oxygen index, and melamine phosphate is non-toxic with a function of increasing flame retardancy because it contains nitrogen, and is particularly useful because it does not contain halogen and is not toxic.

In addition, dimethylpolysiloxane is added to enhance the antifouling function according to chemical resistance and water repellency, and to secure antifoaming properties, and Reineke salt and sodium alkylbenzenesulfonate are added to secure acid resistance.

In addition, prostaglandin is a fatty acid derivative consisting of 20 carbons, which is further added to enhance the effect of killing and removing decomposition by inhibiting bacterial activity, and DBNPA (2,2-Dibromo-3-nitrilopropionamide) is a liquid antibacterial agent that causes mold in particular. It is one of the clay minerals and has an anion, so it causes coagulation and precipitation through electrical neutralization and suspended particles of positive ions, adsorbing and decomposing heavy metals, toxic gases, and harmful substances. It has excellent bacteriostatic and sterilizing effects of viruses, bacteria and fungi, of course, so it is further added for antibacterial, antiviral and sterilization, adsorption and decomposition of harmful substances.

At this time, the surface of the drawer 130 on which the coating layer was formed was tested for flame retardancy according to ASTM D2863-17, and as a result, it was determined as V-2, and it was confirmed that flame retardancy was secured. In addition, it was confirmed that it has antibacterial properties in the antibacterial activity test against fungi.

In addition, as a result of checking the antistatic characteristics according to the standard of JIS T8 103, it was confirmed as 0.51×108Ω, which is within the range of 1×10 ⁵ Ω ≤ R (resistance) ≤ 1×10 ⁹ Ω, and has good antistatic characteristics. Became.

In addition, in the present invention, even in the case of the cabinet body 110 and the partition plate 120 made of wood, it is necessary to post-process to have functional characteristics. This is also because there is no meaning of forming a coating layer on the drawer 130 when only the drawer 130 is post-processed and the cabinet body 110 and the partition plate 120 are not processed.

Therefore, in the present invention, the cabinet body 110 and the partition plate 120 of these wooden materials are also processed, but since they are wood, the coating solution is deeply anchored by activating the voids, so that coating stability can be secured. It is desirable to configure.

To this end, the cabinet body 110 and the partition plate 120 are applied in a preheating chamber maintained at 30-40° C. for about 1 hour-1 hour and 30 minutes before applying the coating liquid and then naturally dried. It must be post-processed in a way.

At this time, the coating liquid was 4.5% by weight of the lower stone powder having a particle size of 0.1 μm, 5.5% by weight of illite powder having a particle size of 0.1 μm, 8.5% by weight of cellulose diacetate, 5% by weight of PTFE, and 1.5% by weight of coal tar. It consists of a weight %, 2.5 weight% of cetose, 3.5 weight% of polyethylene glycol phenyl ether, 1.5 weight% of silicone, 2.5 weight% of sorbitan oleate, 15 weight% of water, and the rest of the modified urethane resin.

Here, Haseok ((Na ₂ OㆍAl ₂ O ₃ ㆍ2SiO ₂ )(K ₂ OㆍAl ₂ O ₃ ㆍ2SiO ₂ ) is a mixture of two compositions and is added to maintain heat resistance, light transmittance, and strength of the coating film. Illite powder is known to have excellent far-infrared radiation, so it can deodorize, deodorize, purify air, and has excellent antibacterial activity against viruses, bacteria, and fungi, and therefore, heavy metals and various induced gases present in water, air, and soil. It is widely used for adsorption, deodorization, and decomposition.

In addition, cellulose diacetate is added to improve the tensile strength, flexural strength, and impact strength of the coating layer because it has a high glass transition temperature due to the pyranose rings constituting the cellulose, and polytetrafluoroethylene (PTFE) ) Is one of the fluorine resins and has excellent water-repellent properties and waterproof properties due to its insulation stability, non-adhesion, and low coefficient of friction.

In addition, coal tar is added to inhibit cracking and reinforce waterproof performance, and cetose is an extract extracted from palm oil and is added to stabilize the emulsion as well as adjust the viscosity and prevent sedimentation of the composition, and polyethylene glycol phenyl ether It is added to prevent agglomeration and ensure uniform dispersibility to induce evenly distributed components exhibiting waterproof and heat insulating properties, and silicone is added to prevent the formation of air bubbles while stirring the composition to block defective coating.

In addition, Sorbitan Oleate is added to maintain the solubilization, emulsification and dispersion stability in an emulsion state.

If configured in this way, durability, water resistance, crack suppression, etc. of the cabinet body 110 and the partition plate 120 can be secured, and thus a longer life can be achieved together with the drawer 130.
