(Embodiment 1)
1 is a perspective view of a refrigerated storage according to Embodiment 1 of the present invention, and FIG. 2 is a cross-sectional view of the refrigerated storage according to Embodiment 1. FIG.

  1 and 2, the refrigerated storage body 1 has a storage room adjusted to the refrigeration temperature, and a door 2 that can be opened and closed is provided on the front surface thereof. The refrigerated storage body 1 is composed of an outer box 3 and an inner box 4, and an inner space is provided with a heat insulating material 5 such as foamed urethane or polystyrene foam. On the storage chamber side of the door 2, a packing 6 is provided for ensuring the hermeticity of the storage chamber.

  A cooling device 21 and an antibacterial device 22 are installed inside the refrigerated storage main body 1 kept in a hermetically sealed state, and this is blown by a blower fan 23 from a device cover 24 arranged on the entire surface of the cooling device 21 or the antibacterial device 22. The internal space of the storage is circulated from the hole as shown by the arrows in FIG.

  Further, a shelf 11 and a case 12 for loading stored items such as food and cosmetics are installed in the storage chamber. A cooling plate 26 is installed on the bottom surface of the case 12. A sealed case 13 and a case lid 14 capable of opening and closing the sealed case 13 are provided on the storage chamber side of the door 2.

  On the storage room surface of the inner box 4 exposed in the space in the storage room, and on the surface of the shelf 11, the case 12, the sealing case 13, the case lid 14, the device cover 24, the cooling plate 26, the water supply tank, the door shelf, etc. A lacquer-containing coating is applied. Although the constituent members forming the respective parts are different in shape and material, they are generally referred to as an interior material 30 in the present invention.

  As shown in FIG. 3, the interior material 30 includes a first coating layer 32 on the surface of the interior substrate 31, a second coating layer 33 on the upper side, and a lacquer-containing coating layer 34 on the outermost surface. Applied. A decorative layer 35 such as a picture or foil is provided between the first coating layer 32 and the second coating layer 33.

  In general, lacquer coating has a characteristic luster and depth on its surface, and the depth increases as time passes, but it must be dried for a long time in a high-humidity atmosphere. Careful attention is required for temperature management, and productivity is poor. This is due to the dehydrogenation reaction of urushiol by the enzyme (laccase) contained in the lacquer and auto-oxidation by oxygen in the air, and the painting process is a laborious and time-consuming work due to the slow reaction. .

In the present invention, such a lacquer-containing paint with improved low workability, for example, photopolymerization containing a monomer or oligomer having an acrylate ester nucleus disclosed in Japanese Patent No. 2821110 and Japanese Patent No. 3833202 Lacquer coating ink, lacquer printing ink, or an epoxy derivative of cashew oil disclosed in JP-A-8-41166 is converted into an acrylate derivative by a chemical reaction, and a photopolymerizable lacquer-containing paint composed of this monomer, Furthermore, a photocurable lacquer-containing lacquer coating containing a cationically polymerizable compound, a photopolymerization initiator, and an auto-oxidized coating film component selected from the group consisting of lacquer and cashew oil disclosed in Japanese Patent No. 4868390 is used. It has been.

  It is generally known that a lacquer coating film has an antibacterial action. Also in the present invention, a lacquered coating film having an antibacterial action is used, and the storage room surface of the inner box 4 covered with the lacquered coating film, the shelf 11, the case 12, the sealed case 13, and the case lid 14 are It is installed with antibacterial effect. Thereby, food etc. can be stored hygienically. Moreover, it can also store without being influenced by the other foodstuffs in a storage, etc. by installing so that the case cover 14 may be opened and closed in the airtight case 13 which has the antibacterial effect. The cooling plate 26 installed on the bottom surface of the case 12 communicates the cooling temperature in the space with high sensitivity by coming into contact with the object such as food.

  In addition, the cooling device 21 adjusts the interior of the storage to a stable temperature by the blower fan 23 and simultaneously circulates the fine particles sprayed from the antibacterial device 22 to the storage, so that the antibacterial effect is achieved on the entire surface of the interior material and the storage space. Is synergistically enhanced.

  Further, a lacquer coating film is also applied to the device cover 24 and gives an antibacterial effect to the air in the space by air circulation, and the periphery of the cooling device 21 where the humidity is likely to be high and the peripheral portion of the discharge hole 25 where condensation is likely to occur Also effective.

  FIG. 3 is an enlarged view of the interior material according to the first embodiment of the present invention, which is configured using a lacquer paint mainly composed of an ultraviolet curable lacquer-containing paint containing 10% or more of a lacquer liquid which is a photocurable lacquer-containing paint. It is sectional drawing.

  In FIG. 3, an interior base 31 of the interior material 30 is made of glass, a synthetic resin plate, a metal plate such as stainless steel or aluminum, for example, a stainless steel plate in this embodiment. The surface of the interior base material 31 is subjected to a light shine treatment by polishing, additional processing of a gloss retaining material, chemical treatment, or the like. The first coating layer 32 is formed on the light shine treatment surface of the interior base material 31, and is formed of a colorless, transparent or colored urethane-based resin paint. Although it is lightly colored, there is also an effect of ensuring adhesion with the interior base material 31. In addition, the decorative layer 35 such as a lacquer is formed of gold powder, colored powder, screw, foil, or the like. The second coating layer 33 is formed on the decorative coating 35 and the first coating layer 32 that becomes the base coloring layer, and is formed of a colorless and transparent urethane-based resin paint. The lacquer-containing coating layer 34 is formed on the second coating layer 33, and is formed of a lacquer coating composed mainly of an ultraviolet curable lacquer-containing coating containing 10% or more of lacquer liquid.

  In the interior material 30 having the above-described configuration, first, the surface of the interior base material 31 is subjected to a photo-shine treatment by polishing, additional processing of a gloss retaining material, chemical treatment, or the like, and the surface is a first coating that becomes a base colored layer. The film layer 32 is applied or printed and dried and cured. Next, a decoration layer 35 referred to as a maki-e is formed by spreading gold powder, colored powder, screw thread, foil, or the like at an appropriate position of the first coating layer 32. In this state, a second coating layer 33 serving as an intermediate coating is formed on the decorative layer 35 and the first coating layer 32. Thereafter, the surface of the second coating layer 33 is coated or printed with a lacquer paint mainly composed of an ultraviolet curable lacquer-containing paint, and in this state, it is irradiated with ultraviolet rays to be dried and cured to complete.

  The formation of the coating layer and the lacquer-containing coating layer 34 on the interior material 30 is completed even if it is performed at the stage of the parts before being completed as an interior member or in a flat state before being processed and formed. It may be performed after making them, and may be selected as appropriate.

Since the interior material 30 formed in this way forms the lacquer-containing coating layer 34 using a lacquer paint mainly composed of an ultraviolet curable lacquer-containing paint, irradiation with ultraviolet rays takes about tens of seconds. It can be dried and cured, and its productivity is significantly improved as compared with the case of using a conventional lacquer paint, enabling mass production. Moreover, since the lacquer-containing coating layer 34 can be dried and cured in about several tens of seconds, the lacquer coating can be repeatedly applied several times to increase the depth, and the productivity can be improved even if it is applied several times. Compared to the case of using a conventional lacquer paint, it can be made excellent.

  In addition, since the lacquer-containing coating layer 34 is formed through the first coating layer 32 having high adhesion, even if the interior base material 31 is a metal plate, the lacquer-containing coating layer 34 is firmly bonded and retained. Durability can be secured.

  In particular, in this embodiment, since both the first coating layer 32 and the second coating layer 33 are made of a urethane resin having a strong adhesive force, more sufficient adhesion durability can be ensured.

  Further, the first coating layer 32 and the second coating layer 33 serving as the base coloring layer have different resin materials and resin compounding ratios, that is, the first coating layer 32 serving as the base coloring layer is an interior base. The second coating film layer 33 has a good adhesion to the lacquer paint mainly composed of an ultraviolet curable lacquer-containing paint and serves as a base colored layer. One coating layer 32 can be made of a resin material having a good adhesiveness or a resin compounding ratio, and in this way, the interior having high adhesion durability to the interior base material 31 of any material. The material 30 can be used.

  In addition, the first coating layer 32 serving as the base coloring layer adheres and holds the decorative layer 35, and when the second coating layer 33 is applied, the gold powder or colored powder constituting the decorative layer 35 is displaced. While preventing and making the design of the lacquer picture with high accuracy, the second coating layer 33 covers the decoration layer 35, so that the adhesion surface with the lacquer-containing coating layer 34 is attached to the decoration layer 35 and the first coating layer. It is also possible to use a single material of only the second resin coating layer 18 instead of two different materials with the layer 32, and in this embodiment, a homogeneous material of only the urethane-based resin coating layer. As compared with a lacquer-coated film layer formed by coating or the like, the reliability of the adhesion durability can be made higher.

  Furthermore, since the first coating film layer 32 is formed on the surface of the interior base material 31, it is used as a decorative interior material having a variety of colors by using this as a base colored layer as in the present embodiment. In addition, for example, as shown in FIG. 4, the interior base material 31 alone or a plurality of interior base materials 31 are connected to give a shade of color X, or to give a gradation that changes color, as shown in Y of the same figure In addition, a partial coloring or gradation can be applied to the upper decoration layer 35 of the light and shade X, or an integrated pattern (decoration layer) can be provided between the doors as indicated by Z in FIG.

  In addition, the shade of the color is such that the first coating layer 32 serving as the base coloring layer is colored at a certain concentration, and several layers of lacquer paint mainly composed of UV-curable lacquer-containing paint are applied. The lacquer-containing coating layer 34 can be attached by changing the film thickness. In this case, since the light transmittance varies depending on the film thickness of the lacquer-containing coating layer 34, the light and shade appear when viewed from the outside. Furthermore, the gradation such as light and shade can also be formed by applying colored powder to the surface of the first coating layer 32 serving as the base colored layer and changing the amount of application. In this case, a pattern is formed in addition to the light and shade. It can also be selected as needed.

  Furthermore, since the surface of the interior base material 31 has been subjected to a light shining treatment, the first coating layer 32 serving as the base coloring layer is made colorless and transparent or light like the second coating layer 33, The appearance of the lacquer-coated film layer 34 when viewed from the surface can be made vivid, and the texture can be made higher.

  The light shining treatment is formed by polishing the surface of the interior base material 31 in the present embodiment or by additional processing of the gloss retaining material or chemical treatment, but is not limited to this, and the outermost layer and What is necessary is just to form in the any coating layer of the lower layer side of the lacquer-containing coating layer 34 which becomes, for example in the case of this Embodiment, in the 1st coating layer 32 or the 2nd coating layer 33 used as a base colored layer It may be formed by adding a photoluminescent material made of metal powder or the like.

  On the other hand, when the interior material 30 formed as described above forms the lacquer-coated film layer 34, the lacquer-coated film layer 34 cures in about several tens of seconds, but at the upper and lower edge portions thereof, the liquid is dripped. May be present.

  Therefore, there is a concern that an unsightly thing may occur when used in this state, but in the present embodiment, the end edge of the interior material 30 is covered with an end cover, so that even if there is liquid dripping or the like, it will be externally applied. It is not visible and can maintain a good appearance.

(Embodiment 2)
5 (a) and 5 (b) are an enlarged sectional view and an enlarged front view of the interior material in the second embodiment. In the figure, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. Only different parts will be described.

  The interior material 30 according to the second embodiment includes a plurality of decorative layers 35 formed on the surface of the first coating layer 32 serving as a base coloring layer. That is, the decoration layer 35 is composed of, for example, three layers 35-1, 35-2, and 35-3, and these are formed using gold powder, colored powder, screw, foil, or the like. Furthermore, in this embodiment, a second decorative layer 37 is also formed on the surface of the lacquer-containing coating layer 34.

  Thereby, in this interior material 30, since the decoration layer 35, for example, a maple, overlaps with 35-1, 35-2, 35-3, a sense of perspective can be given to the design. In addition, since the second decorative layer 37 is also formed on the surface of the lacquer-coated film layer 34, the decorative layer of the 35-1, 35-2, 35-3 and the second decorative layer 37 A sense of perspective can be expressed even between. Therefore, the texture of the interior material 30 can be made higher.

(Embodiment 3)
FIG. 6 is an enlarged cross-sectional view of the interior material in the third embodiment. The same parts as those in Embodiments 1 and 2 are denoted by the same reference numerals, description thereof is omitted, and only different parts are described.

  The interior material 30 of Embodiment 3 forms a third decorative layer 38 on the further surface side of the second coating layer 33, and the same as the first coating layer 32 and the second coating layer 33 from above. A third coating layer 36 is formed as an intermediate coating made of a urethane resin coating, and a lacquer-containing coating layer 34 is formed on the surface thereof. The third coating layer 36 is set so that the refractive index of light is lower than the refractive index of the lacquer-containing coating layer 34 by adjusting the urethane resin particles.

  Thereby, in this interior material 30, a feeling of depth increases due to the difference in refractive index between the lacquer-containing coating layer 34 and the third coating layer 36, and the texture becomes higher. Moreover, the presence of the third coating layer 36 having a low refractive index in the lower layer of the lacquer-containing coating layer 34 allows the second coating layer 33 or the first coating layer 32 to be the base coloring layer, or the interior base. It is possible to suppress the reflection of the light shining layer formed on the material 31 to give a harsh depth feeling and to further improve the texture.

(Embodiment 4)
FIG. 7 is an enlarged cross-sectional view of the interior material in the fourth embodiment. In the figure, the same parts as those in the first to third embodiments are denoted by the same reference numerals, and the description thereof is omitted. Only different parts will be described.

  The interior material 30 of Embodiment 4 forms the recessed part 39 by the laser processing etc. on the surface of the interior base material 31, and forms the 1st coating layer 32, the decorating layer 35, and 2nd coating used as a base colored layer on it. A film layer 33 and a lacquer-containing coating layer 34 are formed.

  As a result, in this interior material 30, the reflection of light by the concave surface of the concave portion 39 varies depending on the angle at which the manner of light refraction of the lacquer-coated film layer 34 is seen, so that the appearance of the pattern formed by the concave portion 39 is changed. Can be further improved in texture. In particular, if the concave portion 39 is colored, the change in appearance can be made clear and effective.

  As mentioned above, in each embodiment, although an example of the household appliance of the present invention and the interior material used for this was shown, the present invention is not limited to the configuration illustrated in each of the above embodiments, Needless to say, the portions may be formed in combination or the lacquer-containing coating layer may be formed as a plurality of layers, and various modifications can be made within the scope of the object of the present invention.

  Moreover, although each said embodiment demonstrated by what formed each coating-film layer and the lacquer-containing coating-film layer 34 on the basis of the interior base material 31, each coating-film layer except the interior base material 31 is made into a film form. It is good also as a specification which forms and affixes on the interior base material 31. FIG. In this case, the quality of each coating layer can be made uniform, and the cost can be reduced.

  Further, when the interior material 30 is a resin, the lacquer coating material or the lacquer material may be previously kneaded into the resin and molded. In this case, the antibacterial effect of lacquer can be held by the interior base material 31 itself, and the interior material 30 can easily have the texture and antibacterial effect of lacquer.
