Description

Cabinet with function for prevention infections disease}

The present invention relates to a storage cabinet having an infectious disease prevention function, and by installing a carbon yarn woven planar heating element that radiates far-infrared rays in a base plate for separating the storage space up and down, it is possible to dry and sterilize clothes or shoes stored in the storage space. It relates to a cabinet with a function of preventing infectious diseases.

Recently, interest in health is increasing due to the spread of infectious diseases such as Corona 19.

Furniture fusion with electronic technology is being introduced, such as a closet for sterilizing and drying clothes by supplying ultraviolet rays, steam or dry hot air, and a shoe rack for removing odors and drying.

However, the existing fusion furniture has a problem that the composition of the cabinet is complicated and the cost of products is increased by installing additional parts such as an ultraviolet lamp for sterilization, a deodorizer for odor removal, and a fan for forced circulation of hot air. Although the deodorizing function is good, there is a problem in that the original function cannot be exhibited due to failure of additional parts and the like over time.

In addition, Published Utility Model Publication No. 20-2014-0001326 discloses a shoe rack that induces an upward flow air flow with a far-infrared radiation sheet attached. It is provided to promote a drying effect, and by using the principle that hot air flows upward, an air inlet is provided at the bottom of the shoe compartment, and when the hot air is discharged to the top of the shoe rack, it is discharged through a deodorant box, thereby eliminating odors indoors. It is described that the odor of the stored shoes is removed, so that whenever you wear the shoes, you can enjoy a dry, sterilized and dry state, and a hygienic management condition can be achieved.'

However, since the conventional utility model embeds a far-infrared radiation means on the side wall of the thread room to radiate heat inside the shoe cabinet, the heated air flows upward, and heat is concentrated upward compared to the lower part. Therefore, heat is concentrated in the upper part more than necessary, whereas the lower part is maintained at a lower temperature than the upper part because external cold air continuously flows in. Therefore, since the temperature difference between the upper and lower parts is formed, there is a problem that the shoes located in the lower part dry more slowly than the shoes located in the upper part. On the other hand, if the lower shoes also want to be dried at a desired time, increasing the driving current of the overall far-infrared radiation means, the lower shoes can also set the desired drying time to some extent, but now more heat is applied to the upper part, power consumption increases. This waste of electricity contributes to an increase in electricity bills in households. Therefore, each household will be reluctant to use or reduce the operation of a shoebox with good functions due to the burden of electricity bills.

Therefore, there is a demand for the emergence of economical and cost-effective products while making use of the practicality of furniture and exhibiting sterilization or deodorization functions without failure for a long time.

In order to solve the problems of the prior art as described above, an object of the present invention is to provide a storage cabinet capable of exerting a sterilization drying effect by far-infrared radiation.

Another object of the present invention is to provide a storage cabinet having an infectious disease prevention function that is economical and energy efficient by maintaining a uniform temperature of the upper and lower portions of the storage space inside the storage cabinet.

Another object of the present invention is to provide a storage cabinet having an infectious disease prevention function capable of increasing the sterilization and drying effect by maximizing the amount of far-infrared radiation to the storage object.

In order to achieve the above object, the storage cabinet having the infectious disease prevention function of the present invention has a main body having a downward airflow passage formed on the left and right side walls constituting the storage space, and a plurality of ventilation holes installed vertically at regular intervals in the storage space in the main body. A plurality of support plates formed, a plurality of carbon yarn woven planar heating elements each installed in the support plate to radiate far-infrared rays, and a control unit for controlling power supply to the carbon yarn woven planar heating elements built into each of the plurality of support plates.

It is preferable that the number of carbon yarns per unit area woven from the bottom to the top of the plurality of carbon yarn woven surface heating elements 130 and 230 is reduced to equalize the upper and lower parts of the storage cabinet. The control unit controls the amount of heat generated by the plurality of carbon yarn woven planar heating elements in response to the temperature at the lower end of the storage space.

The hot air formed inside the storage space by the heat generated from the plurality of carbon yarn woven planar heating elements forms an upward airflow flowing upward through the plurality of ventilation holes of the plurality of support plates, and the hot air raised upward is The upper and lower portions of the storage space are uniform by circulating the interior of the storage space from the center to the left and right side walls by forming a downward airflow that flows downwards along the downdraft passages formed on both sidewalls as the temperature drops while dissipating heat from the left and right side walls to the outside. Controlled by drying temperature. It is to provide a storage cabinet with an infectious disease prevention function to sterilize and dry clothes or shoes stored at each end of the storage space by far-infrared rays radiating up and down from each of the carbon yarn woven planar heating elements. A storage cabinet with an infectious disease prevention function is provided.

As described above, the storage cabinet having the function of preventing infectious diseases according to the present invention can prevent the spread of infectious diseases because it is possible to dry and sterilize the stored clothes or shoes by radiating far-infrared rays using a carbon yarn heating fabric. In addition, since the heating value of the base plate at the bottom is generated higher than that of the base plate at the top, the natural convection inside the storage space can induce air circulation without a fan, so that the temperature of the upper and lower parts of the storage space can be maintained evenly. It is economical because it can maximize the effect of dry sterilization by consumption of energy.

However, the effects of the present invention are not limited to the above-mentioned effects, and other effects not mentioned above may be clearly understood by those skilled in the art within the scope not departing from the spirit and scope of the present invention.

Hereinafter, a specific embodiment of the storage cabinet having an infectious disease prevention function according to the present invention will be described in detail.

1 is an exterior front view of a preferred embodiment of a storage cabinet having an infectious disease prevention function according to the present invention, FIGS. 2 to 4 are views for explaining the internal configuration of FIG. 1, and FIG. 5 is a woven surface of the carbon yarn of FIG. It is a view for explaining the power supply state of the heating element.

Referring to the drawings, the storage cabinet 100 having an infectious disease prevention function is applied to the shoe storage cabinet, that is, the shoe cabinet 100, and the body 110, the base plate 120, the carbon yarn woven planar heating element 130, and the control unit 140 Includes.

The main body 110 has a box-type cabinet structure having a storage space 112 therein by assembling a plate material on the top, bottom, left, right, and rear, and a double-open door 114 is installed on the front side.

In the main body 110, four support plates 120:122, 124, 126, and 128 are installed at regular intervals up and down. A plurality of ventilation holes 129 are formed in the support plates 122, 124, and 126. The ventilation holes 129 are provided as a passage through which hot air at the bottom passes to the top.

Downdraft passages 110a and 110b are formed between the left and right side walls of the body 110 and both side ends of the base plate, respectively. The downdraft passages 110a and 110b are provided as passages through which downdraft flows indicated by arrows descending along both side walls flow, as shown in FIG. 2.

In the base plate (122, 124, 126, 128), each of the carbon yarn weaving planar heating elements (130:132, 134, 136, 138) are built. In FIGS. 3 and 4, only the carbon yarn woven planar heating element 138 inside the base plate 128 is shown. Each of the support plates 122, 124, 126, and 128 may be electrically connected to the control unit through a contact portion on one side of which is mounted on a mounting groove or a mounting protrusion provided on the left and right side plates.

The carbon yarn woven planar heating elements 130:132, 134, 136, and 138 are connected in parallel to the control unit 140 through wires 142 and 144 accommodated in the right wall to receive power.

The carbon yarn woven planar heating element 130:132, 134, 136, 138 is composed of the carbon yarn heating fabric 10 shown in FIGS. 6 to 9. The carbon yarn woven planar heating elements 130:132, 134, 136, and 138 are designed to generate different amounts of heat per unit area. That is, it is designed to gradually decrease the amount of heat generated in each stage from the bottom to the top.

As shown, the carbon heating fabric 10 according to the present invention is a linear heating element formed by weaving a certain area of a polyester yarn 11, a carbon coating yarn 12, and a stone copper wire 13 in a mesh form. The carbon heating fabric 10 is formed by weaving a weft yarn and a warp yarn in a direction orthogonal to each other. The polyester yarn 11 is used for both weft and warp yarns, the carbon coating yarn 12 is used only for weft yarns, and the stone copper wire 13 is intensively arranged only in the left and right rims, so that the carbon coating yarn 12 and the electrical It is connected by Seokdong wire 13 is connected to the power supply line 14. A polyester thread 11 is disposed on the left and right sides of the stone copper wire 13 to hold the position of the stone copper wire 13. The polyester thread 11 serves to form a skeleton in the form of a basic mesh so that the carbon coating thread 12 and the stone copper wire 13 are formed in the form of a planar heating element. The polyester yarn 11 is woven orthogonally to each other with a weft yarn and a warp yarn to form a skeleton having a desired size. The carbon-coated yarn 12 is woven in the form of weft yarn and warp yarn by the polyester yarn 11, and the stone copper wire 13 is woven on the left and right edges in the form of warp yarn. Due to this structure, since the carbon coating thread 12 and the stone copper wire 13 are woven by the polyester thread 11, structural stability is maintained and the shape can be used without deformation at regular intervals for a long time without being pushed. When power is supplied to the carbon coating seal 12, a resistance value is given to generate heat. The carbon coating seal 12 is manufactured to have a resistance value required for a heating element for a cabinet after impregnating the branded carbon with aramid yarn twisted in 2 or 3 depending on the product type. The stone copper wire 13 serves to supply power to the carbon coating chamber. Seokdong wire 13 is connected to the power supply line 14. The stone copper wire 13 is arranged on both sides of the carbon heating fabric 10 in a set of 20-40 strands. The stone copper wire 13 is formed of a conductor made of tin as a base material. The power supply line 14 is connected to a commercial power source to supply power to the Seokdong line 13. It is preferable that the power supply line 14 is provided with a Teflon wire. Teflon wire is a 200℃ heat-resistant wire that stably supplies power even at high temperatures. Here, the distance between the weft yarn and the warp yarn formed by the polyester yarn 11 and the carbon coating yarn 12 may be variously adjusted. In addition, the distance and density at which the carbon coating yarns 12 are disposed between the polyester yarns 11 may be adjusted differently depending on where the carbon heating fabric 10 is used. The number of repeated rows of the polyester yarn 11 and the carbon coating yarn 12 may be variously adjusted. The carbon heating fabric 10 according to the present invention is not formed only with the carbon coating yarn 12, but is formed by woven together in a planar structure formed by using the polyester yarn 11 as a weft yarn and a warp yarn. As a result, the carbon coating chamber 12 may be disposed in a certain area at uniform intervals, and the amount of heat generated may be adjusted according to the disposition interval. In addition, since the heat emitted from the carbon coating chamber 12 has a long wavelength, the heat is radiated without staying on the surface, so space heating can be performed with a large amount of heat radiation even at high temperatures without causing thermal burns. In addition, it is a self-regulating heating element (SR heating element) that performs a temperature self-regulation function to keep the temperature in a predetermined area constant, and maintains a constant temperature while adjusting the heating state in response to the surrounding temperature environment. Can be reduced.

Therefore, in the present invention, as shown in Table 1 below, power consumption and heating temperature are designed differently from each other by varying the number of rows of carbon coating seals 12 per unit area.

That is, the lowermost carbon yarn woven planar heating element 132 has a heating temperature of 60°C, a two-stage carbon yarn woven planar heating element 134 has a heating temperature of 50°C, and a three-stage carbon yarn woven planar heating element 136 Is composed of a heating temperature of 45 ℃, the uppermost carbon yarn woven planar heating element 138 may be configured with a heating temperature of 40 ℃. Therefore, as shown in Fig. 2, the hot air heated first at the bottom forms a rising airflow (arrow), and the rising airflow rises to the top through the vent holes 129 in the 2nd and 3rd stages, so the calorific value of the top is at the bottom. By designing with a relatively small value compared to the calorific value of, it is possible to exhibit effective drying and sterilization efficacy while reducing power consumption. In the case of the carbon yarn woven planar heating element 132, as a result of a test commissioned by the Korea Far Infrared Association, the emissivity of the far-infrared rays of 5 to 20 μm was measured as 0.903 as shown in FIG. 10, and the radiated energy was as shown in FIG. Likewise, it was measured as 4.78×10 power (W) (here, the test method is KFIA-F1-1005, which is the measurement result compared to a black body using an FT-IR spectrometer).

Accordingly, the carbon yarn woven planar heating elements 130:132, 134, 136, and 138 radiate far-infrared rays, thereby exerting sterilization efficacy of bacteria or viruses contaminated in the shoes stored in the storage space. This far-infrared sterilization effect prevents the occurrence of mold and the like, thus preventing the occurrence of odor and exerting the effect of removing odor.

Therefore, without additional installation of a separate ultraviolet lamp or deodorizer, it is possible to exhibit the efficacy of sterilization and odor removal only by installing a base plate with a carbon yarn woven planar heating element. It can have non-high marketability.

In this embodiment, the control unit 140 may control the power supply of the entire four-stage carbon yarn woven planar heating element in response to a temperature sensor that detects the temperature of the lowermost carbon yarn woven planar heating element that generates high temperature heat.

12 is a bird's-eye view of another preferred embodiment of a storage cabinet having an infectious disease prevention function according to the present invention, and FIGS. 13 and 14 are views for explaining the internal configuration of FIG. 12.

Referring to the drawings, a cabinet having an infectious disease prevention function is applied to a closet or built-in cabinet 200, and includes a main body 210, a base plate 220, a carbon yarn woven planar heating element 230, and a control unit 240. .

The main body 210 has a box-type closet structure having a storage space 212 therein by assembling a plate material on the top, bottom, left, right, and rear, and a double-open door 214 is installed on the front side.

In the main body 210, three support plates 220 (222, 224, 226) are installed at regular intervals up and down. A plurality of ventilation holes 229 are formed in the support plates 222, 224, 226. The ventilation holes 229 are provided as a passage through which hot air at the bottom passes to the top. In the base plate (222, 224, 226), carbon yarn weaving planar heating elements (230: 232, 234, 236) are built in, respectively. Each of the support plates 122, 124, and 126 is mounted on a mounting groove or a mounting protrusion provided on the left and right side plates, and is connected to the power supply lines 242 and 244 through a mounted contact portion, thereby being electrically connected to the control unit 240. . The carbon yarn woven planar heating element 230 (232, 234, 236) is connected in parallel to the control unit 240 through wires 242, 244 accommodated in the right wall to receive power.

Downdraft passages 210a and 210b are formed between the left and right side walls of the body 210 and both side ends of the base plate, respectively. The descending airflow passages 210a and 210b are provided as passages through which the descending airflow indicated by arrows descending along both side walls flows, as shown in FIG. 14.

The carbon yarn woven planar heating elements 230:232, 234, and 236 are composed of the carbon yarn heating fabric 10 shown in FIGS. 6 to 8 described above. The carbon yarn woven planar heating elements 230 (232, 234, 236) are designed to generate different amounts of heat per unit area. That is, it is designed to gradually decrease the amount of heat generated in each stage from the bottom to the top.

Therefore, in the present invention, as shown in Table 2 below, power consumption and heating temperature are designed differently by varying the number of rows of carbon coating yarns per unit area.

That is, the lowermost carbon yarn woven planar heating element 232 has a heating temperature of 60°C, the two-stage carbon yarn woven planar heating element 234 has a heating temperature of 50°C, and the uppermost carbon yarn woven planar heating element 236 is The heating temperature can be configured as 45℃. Therefore, as shown in Fig. 13, the hot air heated first at the bottom forms an upward airflow (arrow), and the upward airflow rises to the upper end through the air vents 229 in the second and third stages, so that the heating value of the upper end is reduced to the lower end. By designing with a relatively small value compared to the calorific value of, it is possible to exhibit effective drying and sterilization efficacy while reducing power consumption. As described above, the hot air formed inside the storage space by the heat generated from the plurality of carbon yarn woven planar heating elements forms an upward airflow flowing upward through the plurality of ventilation holes of the plurality of support plates (FIGS. 2 and 14). The number of solid arrows indicates the difference in the amount of heat generated in each stage), and the hot air rising upward dissipates heat from the left and right side walls of the main body to the outside, while the temperature drops and the downward airflow passages 110a, 110b, 210a, formed on both side walls, The upper and lower portions of the storage space are controlled to a uniform drying temperature by circulating the interior of the storage space from the center to the left and right side walls by forming a downward airflow along 210b) (the solid downward arrow in Figs. 2 and 14) ( As indicated by the dotted arrow in FIG. 2, the upper and lower portions maintain the temperature with a uniform amount of heat).

However, as shown in FIG. 15, in the prior art, since far-infrared radiation sheets are installed on both side walls, heat or radiant energy is transferred only from both side walls to the inner space. Therefore, since heat is generated uniformly in the upper and lower parts, the temperature of the upper part where the rising air flow rises is maintained higher than the lower part (the number of dotted arrows indicates the temperature distribution). In addition, cold air is introduced from the outside through the through hole in the lower part, and the inflowed cold air is made into hot air by the heat supplied from both side walls as it rises upward to form an upward airflow, and the hot air concentrated in the upper part is externally through the deodorant box. It is a structure that wastes power due to heat loss because it is emitted as

In addition, since far-infrared rays, which are radiant heat from both side walls, are radiated to the inside, the amount of far-infrared rays applied to the storage object is small, and the amount of far-infrared rays decreases toward the center away from both side walls. Therefore, the upper and lower temperature deviation is severe, and the far-infrared radiation amount also has a deviation between the center and both side walls.

However, in the storage cabinet of the present invention described above, by designing different amounts of heat in the upper and lower portions, the overall upper and lower temperatures are maintained uniformly when heat is transferred by the rising air flow, and since each base plate radiates up and down the far-infrared rays, uniform far-infrared radiation is achieved regardless of the vertical and horizontal divisions. You lose.

As described above, in the embodiment of the present invention, a shoe cabinet and a closet have been described, but the present invention is not limited thereto, and may be applied to cabinets or furniture of various sizes.

The above description is merely illustrative of the technical idea of the present invention, and those of ordinary skill in the art to which the present invention pertains will be able to make various modifications and variations without departing from the essential characteristics of the present invention.
