Description

[0001] The present invention relates to an ultraviolet ray sterilizer having scattered reflection structure,

The present invention relates to an ultraviolet sterilizer, and more particularly, to an ultraviolet sterilizer having a diffusive structure in which an ultraviolet ray can efficiently reach a sterilizing object located inside an ultraviolet sterilizer.

The dishes are kept in a washing process every meal. Cleaned dishes are divided into different sanitary conditions depending on storage location. If moisture is not dried smoothly or temperature is high, it is a good condition for propagation of bacteria, fungi and viruses. Where a large amount of tableware such as a restaurant or a foodservice station is provided, an ultraviolet sterilizer is arranged and used to suppress the propagation of bacteria, fungi, and viruses, and to provide sterilization. This is one of the obligations of sanitary law to sterilize dishes to provide safe food.

The ultraviolet rays used in the sterilizer are known to inhibit bacteria, fungi and viruses with a wavelength of 250 to 260 nm. Ultraviolet sterilizers are widely used, and they are manufactured in various structures and commercialized. However, the conventional ultraviolet sterilizer differs in the sterilizing effect of a tableware located near a light source emitting ultraviolet rays and a tableware located far away. The reason is that the light source that emits ultraviolet light is mainly fixed to the ceiling or side, and the ultraviolet light emitted from the ultraviolet light is struck by the utensils located in the ultraviolet sterilizer. As the plates are stacked or the number of tableware is increased, the sterilizing effect of the tableware located in the place where the wavelength is covered naturally falls. Also, the more sterilized dishes are placed in the sterilizer, the less sterilization effect.

To solve these problems, Korean Patent Application No. 10-2013-0022053 discloses an ultraviolet sterilizer using a diffusive structure, but the diffuse reflection means is provided only on the surface to which the ultraviolet lamp is attached, that is, on the inner ceiling of the ultraviolet sterilizer, On the other side, there is no diffuse reflection means, and the range of ultraviolet wavelength irregular reflection is limited and not efficient.

The present invention provides an ultraviolet sterilizer having a diffusive structure that allows ultraviolet rays to be effectively transmitted to almost all areas of all the objects located inside the ultraviolet sterilizer.

The ultraviolet sterilizer according to one aspect of the present invention includes a main body built-in portion for sterilizing a plurality of objects using ultraviolet rays, a main body enclosure having an inner surface spaced apart from the main body by a predetermined distance, A heater module for heating the air introduced through the air purifying module and supplying the heated air to the main body built-in part, and a heater module for heating the main body built- And a door for opening and closing the part.

The main body built-in unit includes an ultraviolet lamp installed on the upper surface of the main body built-in unit, diffuse reflection means for diffusing ultraviolet rays emitted from the ultraviolet lamp, a plurality of shelves holding the objects, And an air outlet for discharging air to the main body enclosure, wherein the main enclosure is formed on a rear surface of the main enclosure to discharge air to the air outlet of the main enclosure And an air inflow portion for introducing air from the outside of the ultraviolet sterilizer.

Wherein the irregular reflection means includes a plurality of protrusions having a polygonal protruding surface over at least both sides of the main body built-in portion and a plurality of depressions having a polygonal recessed surface between the adjacent protrusions in a continuous pattern And the shelf has a structure or material capable of transmitting the ultraviolet rays emitted from the ultraviolet lamp and the ultraviolet reflected by the irregular reflection means.

Wherein the irregular reflection means includes a plurality of protrusions having a polygonal protruding surface and a plurality of depressions having a polygonal recessed surface between adjacent protrusions over the entire upper surface of the main body built- And a concave-convex member formed in a continuous pattern in the predetermined pattern.

The diffusive reflecting means may include a plurality of protrusions having a polygonal protruding surface and a plurality of depressions having a polygonal recessed surface between the adjacent protrusions continuously over a whole rear surface of the main body built- And may further include a concave-convex member formed therein.

The irregular reflection means includes a plurality of protrusions protruding in a polygonal pyramid shape over the entire lower surface of the main body built-in portion, and a plurality of depressions linearly recessed between adjacent protrusions are continuously formed in a predetermined pattern, As shown in FIG.

Wherein both side surfaces of the main body built-in portion opposite to each other are inclined so that a distance between the both side surfaces is narrowed and widened repeatedly, and a plurality of protrusions having a polygonal protruding surface on the inclined side surfaces, A plurality of depressions each having a depressed shape of a polygonal shape are formed between the protrusions, the depressions being formed by concaves and convexes of a continuous pattern in a constant pattern, and between the side portions having the narrowest gap between the inclined sides, Shelves can be mounted.

The irregular reflection means may have irregularly reflecting means integrated with the inner surface forming a concavity and convexity directly on the inner surface of the main body built-in portion.

The irregular reflection means may include diffuse reflection means, which is a separate concave-convex panel attached to the inner surface of the main body built-in portion.

The shelf may have a network structure in which ultraviolet rays emitted from the ultraviolet lamp and ultraviolet rays reflected by the diffusive reflecting means can be transmitted.

The shelf may be made of a material of ultraviolet-transmissive glass through which ultraviolet rays emitted from the ultraviolet lamp and ultraviolet rays irregularly reflected by the diffusive reflection means can be transmitted.

In the ultraviolet sterilizer having a diffusive structure, ultraviolet rays emitted from the ultraviolet lamp are equally distributed on the inner surface of the ultraviolet sterilizer, so that the ultraviolet rays emitted from the ultraviolet lamp reach the almost entire area of the objects placed inside the sterilizer. Since the ultraviolet ray emitted from the ultraviolet ray lamp is irregularly reflected by the diffused reflection means and reaches all the places inside the ultraviolet ray sterilizer, a smaller number of ultraviolet ray lamps are required to sterilize the objects located inside the ultraviolet ray sterilizer. This can reduce the power consumption due to the ultraviolet lamp and reduce the manufacturing cost and the maintenance cost of the ultraviolet sterilizer. In addition, the shelf on which the object is placed can be designed to have a structure or material through which ultraviolet rays can be transmitted, so that ultraviolet rays can be more effectively reached and sterilized by the objects placed inside the sterilizer.

Ultraviolet light is used for sterilization because it is useful only for ultraviolet rays. Although the amount of energy to be irradiated is different, it is effective for almost all species, and it does not change the objects placed inside the ultraviolet sterilizer, and is simple and economical compared to a method of sterilizing by heating or chemical treatment. The ultraviolet wavelength range is 100 to 400 nm, UV-C (short wave) is 100 to 240 nm, UV-B (medium wave) is 240 to 125 nm and UV-A It is totally different according to the wavelength of ultraviolet ray. Ultraviolet ray of 250 ~ 260nm wavelength is most effective for sterilization.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the embodiment of the present invention described below, a light source that artificially emits a wavelength of 253.7 nm is provided and examined even in a range of 250 to 260 nm. In addition to the wavelength of 253.7 nm, the wavelength range can be adjusted depending on the type of target bacteria, fungus and virus. The amount of ultraviolet light to be irradiated is directly proportional to [Radiant Intensity X irradiation time], but the longer the exposure to strong ultraviolet rays, the higher the sterilizing effect. However, since sterilizing ability is not available, the sterilized tableware is not exposed to environments where bacteria, mold, It is preferable to keep it by blocking it from the outside, and to remove it only when it is used. In addition, since ultraviolet rays are harmful to eyes and skin, ultraviolet sterilizer doors use materials that can be sunk or UV rays.

1 is a perspective view of an ultraviolet sterilizer 100 having a diffusive structure according to an embodiment of the present invention. Referring to FIG. 1, the housing of the ultraviolet sterilizer 100 according to the present embodiment includes a main body built-in portion 12 of a rectangular box external appearance sterilizing a plurality of objects using ultraviolet rays, And a door 15 for opening and closing the main enclosure 12 and the main enclosure 11. The main enclosure 12 and the main enclosure 12 enclose the main enclosure 12, . The inner surface of the main body built-in portion 12 is provided with an upper surface to which the ultraviolet lamp 16 is attached, a lower surface positioned horizontally facing the upper surface to which the ultraviolet lamp 16 is attached, Two sides facing the door 15, a door 15 facing the door 15 in a closed state, and a top surface, a bottom surface, and a rear surface bent at a right angle from the side surfaces.

The ultraviolet lamp 16 provided on the upper surface of the main body built-in part 12 emits ultraviolet rays into the main body built-in part 12 where the sterilizing objects are located. The upper surface, the lower surface, the side surfaces, and the rear surface of the main body built-in portion 12 are arranged in the main body built-in portion 12 in order to allow the ultraviolet rays emitted from the ultraviolet lamp 16 to reach the inside of the main body built- It is designed with diffuse reflection structure. The irregular reflection means provided on the inner surface of the main body built-in portion 12 may be formed as an inner surface integral type which directly forms the unevenness on the inner surface of the main body built-in portion 12, And may be configured in a panel form. The irregular reflection means provided on the inner surface of the main body built-in portion 12 will be described in detail with reference to FIG. 5 to FIG.

1, the open side of the main enclosure 11 is located on the open side of the main enclosure 12 and the inside of the main enclosure 12 through the open side of the main enclosure 12, The sterilizing object can be put in or removed from the inside thereof. A rectangular plate-shaped door 15, which is coupled to the main body enclosure 11 so as to be rotatable about one corner of the open face of the main body enclosure 11, The glass is coated with an ultraviolet shielding film made of vinylidene chloride, so that the ultraviolet ray shielding film is irregularly reflected from the main body built- Thereby blocking the wavelengths. The ultraviolet shielding film provided on the glass of the door 15 may be replaced with another material capable of blocking ultraviolet rays. Such a material is well known in the technical field to which this embodiment belongs, and a detailed description thereof will be omitted.

The main body built-in part 12 is provided with a shelf 13 on which sterilizing objects are placed at regular intervals from the upper surface to the lower surface where the ultraviolet lamps 16 are installed. The shelf 13 has a structure or material capable of transmitting the ultraviolet rays emitted from the ultraviolet lamp 16 and the ultraviolet rays reflected by the diffuse reflection means provided on the inner surface of the main body built- For example, the shelf 13 may have a network structure in which ultraviolet rays emitted from the ultraviolet lamp 16 and ultraviolet rays reflected by the irregular reflection means provided on the inner surface of the main body built- The shelf 13 in the form of a rectangular plate having a mesh structure can be made of stainless steel so as to withstand the loads of the objects. This mesh structure provides excellent ventilation and allows diffused ultraviolet light to reach the inside and outside of the objects placed on the shelf 13 evenly.

The shelf 13 may be made of a material of ultraviolet ray transmitting glass that can transmit the ultraviolet rays emitted from the ultraviolet lamp 16 and the ultraviolet rays reflected by the diffuse reflection means provided on the inner surface of the main body built- Ultraviolet ray-transmitting glass contains quartz or borosilicate, and passes ultraviolet rays. Ultraviolet-transmissive glass is not superior in ventilation compared to a net structure, but it does not have ultraviolet blocking by the flesh constituting the net. Further, the shelf 13 may be fabricated with a network structure of ultraviolet-transmitting glass material. Ultraviolet rays that can not transmit a solid or opaque material are reflected a number of times through irregular reflection means provided on the inner surface of the main body built-in part 12, and when the light reaches the objects, the shelf 13 of the mesh structure does not have a barrier force A larger number of diffuse reflections occur in a shorter time. This results in sterilization of the wider area of the object in a shorter time.

 The shelf 13 can be installed inside the main body built-in part 12 by the receiving means 14 provided on the wall surface of the main body built- The supporting means 14 may be formed of a square rod-like member attached to both side surfaces of the main body built-in portion 12 as shown in FIGS. 3 and 4, which will be described later, And may be formed of an oblique sloped surface formed. The details of this will be described later with reference to FIG. 3 and FIG. The shelf 13 can be horizontally spaced by a predetermined distance between the upper surface and the lower surface of the inner space of the main body built-in part 12 by the receiving means 14. [ The shelf 13 is detachable with respect to the receiving means 14 because it is in the form of a rectangular plate having a net-like structure as described above. For example, it is possible to remove all of the shelves 13 to clean the main body built-in part 12, or to remove some of the shelves 13 to sterilize a somewhat larger object, 13) Replacement is easy when it is broken.

FIG. 2 is a sectional side view of the ultraviolet sterilizer 100 shown in FIG. 1, showing the structure between the main enclosure 11 and the main enclosure 12 of the ultraviolet sterilizer 100, not shown in FIG. 2, the ultraviolet sterilizer 100 according to the present embodiment is disposed between the main body built-in portion 12 and the main body exterior portion 11 for ventilation and drying of objects, and purifies the air introduced into the main body exterior portion And a heater module 22 for heating the air introduced through the air purification module 21 and supplying the heated air to the main body built-in unit 12. The main body built-in unit 12, Air inlet portions 23a and 23b of the main enclosure 11 and air outlet portions 24a and 24b.

The main body built-in portion 12 is formed on the rear surface of the main body built-in portion 12 and includes an air inflow portion 23a for introducing air from the main enclosure 11 and air The main body enclosure 11 is formed on the rear surface of the main enclosure 11 and includes an air discharge portion 24a for discharging air to the air discharge portion 24a of the main body built- 24b and an air inflow portion 23b for introducing air from the outside of the ultraviolet sterilizer 100. [

The air discharge portion 24a is formed on the rear surface of the main body built-in portion 12 between the upper surface of the main body built-in portion 12 and the first shelf 13 spaced apart from the upper surface by a predetermined distance, The air discharge portion 24b is formed in the rear surface portion of the main enclosure 11 adjacent to the air discharge portion 24a of the main body 12. That is, the main body built-in portion 12 and the air exhaust portions 24a and 24b of the main enclosure 11 are positioned close to each other so that the distance of air escaping is shortened so that the exhausted air is introduced into the ultraviolet sterilizer 100 I did not stay long.

The air inlet portions 23a and 24b are also designed adjacent to the main body built-in portion 12 and the main enclosure 11 at the lower end thereof. An air inlet portion 23a is formed in a rear portion of a main body built-in portion 12 between a lower surface of the main body built-in portion 12 and a first shelf 13 spaced apart from the lower surface of the main body built- The air inlet portion 23b of the main enclosure 11 is formed on the rear surface of the main enclosure 11 adjacent to the air inflow portion 23a of the main enclosure 11. [ The heater module 22 and the air purification module 21 are connected between the main body built-in portion 12 and the air inflow portions 23a and 23b of the main body enclosure 11 to provide clean air to the main body built- The inside of the ultraviolet sterilizer 100 is ventilated and the objects are dried.

The heater module 22, the air purifying module 21, the air inflow portions 23a and 23b and the air exhaust portions 24a and 24b shown in FIG. 2 are used to increase the sterilizing effect of the ultraviolet sterilizer 100 using ultraviolet rays . Most bacteria do not die well even if they are exposed to ultraviolet rays. This means that bacterial, mold and virus sterilization can not be performed smoothly unless the moisture is removed regardless of ultraviolet irradiation. Accordingly, in this embodiment, in addition to the ultraviolet lamp 16 for irradiating ultraviolet rays, the heater module 22 for removing moisture, the air purification module 21, the air inflow portions 23a and 23b, and the air discharge portion 24a And 24b, thereby maximizing the effect of ultraviolet sterilization.

A partition wall 25 is provided in a space between the main body built-in portion 12 and the main enclosure 11 where the heater module 22 and the air purification module 21 are provided, The flow spaces can be separated from each other. If the partition 25 does not exist, the discharged air can stay in the space between the main body built-in portion 12 and the main body enclosure 11 and can block the flow of the discharged air, The heater module 22 and the air-cleaning module 21 may overheat due to the hot air coming out of the heater module 10, which may cause a malfunction phenomenon.

3 is a view showing an example of a front section of the main body built-in section 12 of the ultraviolet sterilizer 100 shown in FIG. 3, the support means 14 for installing the shelf 13 in the internal space of the main body built-in portion 12 includes rectangular bar-shaped members 31 attached to both sides of the main body built- ≪ / RTI > When the objects are placed on the shelf 13, the square bar shaped members 31 facing each other should be installed at the same height on both sides of the main body built-in part 12 so that they do not move to either side. As shown in FIG. 1, the upper surface, lower surface, side surfaces, and the rear surface of the main body built-in portion 12 can be designed with a diffusive structure, and the convexly projecting support means 14 is also opaque It can be used as a diffuse reflection means because it is made of a solid metal material.

Fig. 4 is a view showing another example of a front section of the main body built-in section 12 of the ultraviolet sterilizer 100 shown in Fig. 4, the supporting means 14 for installing the shelf 13 in the internal space of the main body built-in portion 12 includes the main body built-in portion 12, And it may be structured such that it is narrowed and widened so as to be widened. The shelves 13 can be mounted between the side portions 41 having the narrowest gap between the inclined side surfaces and both side portions having the narrowest interval between the inclined side surfaces are formed at the same height, So that they can be mounted horizontally.

The ultraviolet lamp 16 provided on the upper surface of the main body built-in part 12 is connected to the side surface of the oblique inclined surface as compared with that of Fig. 3, which is a side surface perpendicularly connected to the upper surface. You can get more ultraviolet rays. In other words, the receiving means 14 shown in Fig. 4 can provide a mounting means for the shelf 13 only by the inclined structure 41 as described above, and can further diffuse ultraviolet rays of a larger amount of light in a shorter time , Which makes it possible to sterilize the object more quickly.

3 and 4, the irregularity structure formed on the main body built-in portion 12 is shown as a concave-convex pattern in which trapezoidal shapes are continuous on the upper surface and both sides of the main body built-in portion 12, Respectively. The ultraviolet sterilizer 100 according to an embodiment of the present invention includes a diffuse reflection means on the inner surface of the main body built-in portion 12 to diffuse ultraviolet rays emitted from the ultraviolet lamp 16 irregularly. The ultraviolet lamp 16 is provided on the upper surface portion of the main body built-in portion 12 recessed in the shape of the ultraviolet lamp and the entire inner surface of the main body built-in portion 16 except the portion provided with the ultraviolet lamp 16 is designed to have a diffuse reflection structure .

3 and 4, the irregular reflection means of the main body built-in portion 12 includes a plurality of protrusions having a polygonal protruding surface over at least both sides of the main body built-in portion 12, Shaped concave and convex portions 32 and 42 formed in a continuous pattern in a predetermined pattern. The irregular reflection means of the main body built-in portion 12 is provided with a plurality of projecting surfaces having a polygonal shape over the entire upper surface of the main body built-in portion 12 except for the mounting portion of the ultraviolet lamp 16, And concavo-convex members 33 and 43 formed in a shape in which a plurality of depressions having a polygonal depression surface are continuously formed in a predetermined pattern between the protrusions and adjacent protrusions.

The ultraviolet rays emitted from the ultraviolet lamp 16 are reduced in sterilizing power as the reflection is repeated due to the reflectance limit of the diffusing means. Therefore, a diffuse reflection means having a structure capable of widening an area capable of directly receiving ultraviolet rays emitted from the ultraviolet lamp 16 is effective for more complete sterilization of objects. Most of the ultraviolet rays emitted from the ultraviolet lamp 16 are incident on both sides of the main body built-in part 12 obliquely because the ultraviolet lamp 16 is provided on the upper surface of the main body built- In order to widen the area of irregular reflection means capable of directly receiving the ultraviolet rays emitted from the ultraviolet lamp 16 and to cause more irregular reflection, Each protrusion has a polygonal protruding surface, and each depression has a polygonal depression.

The above-mentioned concave-convex members 32 and 42 can be formed on the rear surface, and the rear surface provided with the concave-convex member 32 and 42 is also incident with the ultraviolet ray obliquely as in both sides,

Most of the ultraviolet light reflected by the diffused reflection means is incident on the upper surface of the main body built-in portion 12 at an angle. The area of the diffusive reflection means capable of directly receiving the ultraviolet rays emitted from the ultraviolet lamp 16 is widened and the more diffuse reflection occurs so as to cause the diffuse reflection elements 32 and 42 on both sides of the main body built- The protrusions of the concave-convex members 33 and 43 on the upper surface of the main body built-in portion 12 have a polygonal protruding surface, and each depressed portion has a polygonal depression. On the other hand, in order to increase the reflectance of the diffuse reflection means, the diffuse reflection means may be made of a material such as aluminum, magnesium oxide or the like having a high reflectance of ultraviolet rays.

The irregular reflection means of the main body built-in portion 12 includes a plurality of protruding members 32 and 42 and protruding / contracting members 33 and 43, And concavo-convex members 34 and 44 formed in a shape in which a plurality of depressions linearly recessed between the protrusions and neighboring protrusions are continuous in a predetermined pattern. Since most of the ultraviolet rays emitted from the ultraviolet lamp 16 are vertically incident on the bottom surface of the main body built-in portion 12 facing the upper surface, the ultraviolet lamp 16 is installed on the upper surface of the main body built-

If the protrusions of the concave-convex members 34 and 44 on the bottom surface of the main body built-in portion 12 have flat projecting surfaces, if the ultraviolet rays emitted from the ultraviolet lamp and vertically incident on the bottom surface of the main body built- It is reflected on the same path as the incident path by a protruding surface and is not used for sterilizing objects. Accordingly, the protrusions of the concave-convex members 34 and 44 on the lower surface of the main body built-in portion 12 have a polygonal pyramid shape so that ultraviolet rays reflected through the neighboring polygonal pyramids can reach the objects Respectively. Particularly, the ultraviolet rays reflected by the concave-convex members 34 and 44 on the lower surface of the main body built-in portion 12 are reflected by the concave-convex members 31-33 and 41-43 of the upper surface and the side surfaces of the main body built- The ultraviolet rays are irradiated to the lower part of the objects which are difficult to be irradiated. That is, as described above, ultraviolet rays emitted from the ultraviolet lamp 16 by the combination of the concavo-convex shapes of the upper surface and the side surfaces of the different main body built-in portions 12 and the concavo-convex shapes of the lower surface of the main body built- So that it can be irradiated almost entirely.

Fig. 5 is a plan view of the irregular reflection means of the top and side surfaces of the main body built-in portion 12 shown in Figs. 1-4; Fig. 6 is a partially enlarged view of the diffusive reflecting means shown in Fig. Sectional view of the diffusive reflecting means shown in Fig. 5-7, the irregular reflection means of the upper surface and the side surfaces of the main body built-in portion 12 are provided between a plurality of protruding portions 51 having an octagonal protruding surface 51 and between adjacent protruding portions 51 A plurality of depressed portions 52 having a rectangular depression 52 are continuous in a pattern in which the sides making up the bottom surface of the projections 51 are in contact with each other.

6, each of the projecting portions 51 is formed of eight projecting surfaces 61 having an octagonal shape and eight inclined surfaces 62 having a trapezoidal shape bent from the octagonal projecting surface 61. Each of the depressed portions 52 Is composed of four inclined surfaces 63 of a triangular shape which are inclinedly recessed. The number of the surfaces of each of the protrusions 51 and the depressions 52 is nine and four, and the diffuse reflection means in which these structures are repeated can have several tens to several hundreds of surfaces. This increases the number of diffusible reflections, So that ultraviolet rays can reach the inside of the main body built-in portion 35 evenly.
