Description

  The present invention relates to a technique related to sterilization and deodorization of footwear that uses ultraviolet rays to sterilize and deodorize footwear. In particular, the present invention is installed in a private room such as a capsule hotel for personal use. The present invention relates to a sterilization and deodorization device that can be suitably used.

  2. Description of the Related Art Conventionally, there has been known an apparatus that accommodates and arranges footwear such as slippers and exerts a sterilizing effect and a deodorizing effect on the footwear. Specifically, for example, Patent Document 1 (Japanese Patent Laid-Open No. 07-255827) discloses a structure in which an ultraviolet lamp and an ozone generator are provided inside the apparatus. In such an apparatus, in addition to the sterilizing effect by ultraviolet irradiation, the deodorizing effect that is insufficient by ultraviolet irradiation alone is achieved by the oxidation of odor components by ozone.

  However, since ozone is concerned about adverse effects on the environment, the sterilization and deodorization apparatus according to Patent Document 1 is not preferable. In addition, the structure for preventing leakage of ozone to the outside is complicated, and there is a problem that the manufacturing cost increases.

  In order to deal with such a problem, for example, Patent Document 2 (Japanese Patent Laid-Open No. 2000-254515) and Patent Document 3 (Japanese Patent Laid-Open No. 2001-120646) irradiate titanium dioxide provided inside the apparatus with ultraviolet rays. A storage body such as a closet or a clog box having a structure that improves the deodorizing effect by chemically decomposing odor components by photocatalytic reaction with titanium oxide has been proposed.

  However, the conventional structures such as the clog box shown in Patent Documents 2 and 3 have not yet been able to exert a sufficient sterilizing and deodorizing effect.

  That is, all of those described in Patent Documents 2 and 3 relate to large storage bodies such as entrance storages, closets, clogs, closets, and sheds that store a large number of footwear, While merely installing an ultraviolet light source, a photocatalytic sheet such as titanium oxide is housed in a part of a wall surface or the like. In addition, Patent Document 2 has a description that even with such a simple structure, a sufficient effect is exhibited by circulation in the storage body by natural convection. The effect cannot be expected.

  In particular, in shoes that require a sterilizing and deodorizing effect, the toe portion is completely covered and formed into a bag shape, and stands up in a peripheral wall shape so as to extend from the toe portion to the heel portion. Since the mouth portion into which the lip is inserted is only opened upward, it is extremely difficult to achieve the sterilization and deodorizing effect by ultraviolet rays or the like to the inner depth of the shoe.

  In particular, for example, in capsule hotels and business hotels, it is required that the businessmen staying in the hotel can sterilize and deodorize the outer shoes and the inner slippers only during the night. However, there has not yet been provided a footwear sterilization / deodorization apparatus that can exhibit a sterilization / deodorization effect that is large enough to meet the actual situation.

  In order to obtain a large sterilizing and deodorizing effect, it is conceivable to increase the intensity of ultraviolet rays, but simply increasing the intensity of ultraviolet rays may cause a portion of the footwear to be irradiated with excessively strong ultraviolet rays. As a result, there is a risk that defects such as alteration due to ultraviolet irradiation may occur at specific parts of the footwear. Therefore, it is not always an effective measure.

Japanese Patent Application Laid-Open No. 07-255827 JP 2000-254515 A JP 2001-120646 A

  Here, the present invention has been made in the background of the circumstances as described above, and the problem to be solved is that it requires ultraviolet irradiation with an excessive intensity enough to damage the footwear. In addition, it is possible to obtain an excellent sterilization and deodorization effect in a relatively short time such as overnight. For example, a footwear sterilization deodorization apparatus suitable for personal use in installation of capsule hotels, business hotels, etc. And to provide a sterilization and deodorization method.

  Hereinafter, the aspect of this invention made | formed in order to solve such a subject is described. In addition, the component employ | adopted in each aspect as described below is employable by arbitrary combinations as much as possible. In addition, aspects or technical features of the present invention are not limited to those described below, but are described in the entire specification and drawings, or can be understood by those skilled in the art from those descriptions. It should be understood that it is recognized on the basis of.

  That is, the feature of the present invention related to footwear sterilization and deodorization device has a rectangular box shape with an open / close door, and a back wall portion and a door wall portion that are spaced apart and opposed to each other on the inside, A footwear sterilization / deodorization apparatus for sterilizing and deodorizing footwear by accommodating and disposing footwear in a storage region defined by a top wall portion, a bottom wall portion, and a pair of side wall portions. Is provided with a partition member having a plurality of through holes, and an upper storage region is formed on the top wall side with the partition member interposed therebetween, and a lower storage region is formed on the bottom wall side. UV irradiation tubes are disposed on the back wall portion of the upper storage area and the back wall portion of the lower storage area so that the upper portion extends from the center in the horizontal direction. The top wall and the back wall are all over the entire surface. Mirror surface processing is applied, and the photocatalyst layer is formed over the entire surface of each of the pair of side wall portions and the door wall portion, while the partition member that forms the bottom portion of the upper accommodation region from the center. Also, a heel placing portion for the upper footwear as the footwear is provided on the back wall portion side, and a toe placing portion for the upper footwear is provided on the door wall portion side from the center, and the lower housing In the bottom wall portion constituting the bottom portion of the region, a foot placement portion for underwear as footwear is provided on the back wall portion side from the center, and the toe placement of the underwear on the door wall portion side from the center It exists in the sterilization deodorization apparatus of the footwear provided with the mounting part.

  In the sterilization deodorization apparatus for footwear structured according to the present invention, the footwear is accommodated and disposed with the toe portion facing the door and the heel portion facing the ultraviolet irradiation tube on the back wall portion, The toe portion is placed farther from the ultraviolet irradiation tube than the heel portion, and the ultraviolet irradiation amount of the toe portion becomes smaller than the ultraviolet irradiation amount of the heel portion. Thereby, it is possible to prevent the amount of ultraviolet irradiation from becoming excessively large at the toe portion, and avoid the possibility of discoloration burn due to ultraviolet rays at the toe, which is a particularly conspicuous part of the shoe.

  On the other hand, an ultraviolet irradiation tube is installed in the upper part of the back wall, and the irradiation tube is positioned almost above the footwear footwear, so that ultraviolet rays are efficiently irradiated to the inner part of the footwear, which tends to be trapped with various bacteria. Thus, the bactericidal effect can be advantageously exhibited. That is, preferably, the ultraviolet irradiator is disposed above the height of the heel of the footwear so as to extend in the horizontal direction, thereby increasing the separation distance between the ultraviolet irradiation tube and the heel. At the same time, the ultraviolet rays irradiated from the ultraviolet irradiation tube are directly inserted into the shoe through the shoe mouth.

  In addition, the use of reflection and re-reflection by mirror finishing applied to all surfaces of the top and back walls makes it possible to irradiate a wide range of footwear, resulting in a wider variety of shoes. The ultraviolet rays are irradiated at a proper incident angle, and the ultraviolet rays are more evenly applied to the entire footwear, particularly the entire interior of the footwear, while suppressing direct irradiation of the ultraviolet rays at the toe portion. As a result, a wide range inside and outside the footwear is sterilized and deodorized almost uniformly and efficiently.

  Further, the photocatalytic layer is formed on the pair of side wall portions and the door wall portion, so that the photocatalytic reaction caused by the side wall portion and the door wall portion is combined with the above-described mirror finishing of the top wall portion and the back wall portion. It is possible to apply over substantially the whole. Thereby, the odor component emitted from the footwear is efficiently chemically decomposed, and the deodorizing effect of the footwear is advantageously exhibited.

  In particular, in this structure, the storage area is divided into an upper storage area and a lower storage area, and the upper and lower shoes are stored and arranged independently, depending on the shape and size of the upper and lower shoes, It becomes possible to change the setting of the shape and size of each accommodation region, the position of the ultraviolet irradiation tube, and the like, and further improvement of the sterilization and deodorizing effects in each footwear can be achieved.

  In addition, because it is possible to dispose of sterilization and deodorizing treatment by accommodating and arranging the upper and lower shoes at the same time, for example, the upper and lower shoes are accommodated and arranged at the time of sleep of a user who does not use both upper and lower shoes. Thus, the sterilization and deodorization treatment may be completed at the time of waking up, thereby obtaining the sterilization and deodorization effect of both footwear effectively using time. The reason why such an effective sterilization and deodorizing effect can be obtained in a short time while sleeping is because it has an excellent sterilizing and deodorizing effect.

  In addition, by allowing the upper accommodation area and the lower accommodation area to communicate with each other through a through-hole provided in the partition member, it is possible to exchange ultraviolet rays in both areas, and to achieve more uniform irradiation light, It becomes possible to efficiently generate convection of air in the entire storage area, and the sterilization and deodorizing effects can be advantageously exhibited based on the advantageous ventilation effect. In particular, by setting the lower storage area as the storage area for the underwear, it is possible to more efficiently make ultraviolet rays incident on the underwear opening through the through hole that opens upward. That is, in general, the upper shoe has a slipper structure and the heel portion does not rise, so that the ultraviolet rays irradiated from the heel side can easily reach the back of the toe, but in the underwear of the shoe structure, the mouth is opened upward. However, in the present invention, ultraviolet rays from the ultraviolet irradiation tube installed in the upper accommodation region through the through hole of the partition member are also accommodated in the lower accommodation region. By being guided to the inside of the shoe, a more effective sterilization and deodorizing effect can be exerted on the shoe.

  Therefore, according to this structure, excellent sterilization and deodorizing effects can be obtained in a relatively short time while suppressing damage caused by excessive local ultraviolet irradiation of footwear.

  In the footwear sterilization deodorization apparatus according to the present invention, a structure in which mirror processing is applied to the upper and lower surfaces of the partition member is preferably employed. According to such a structure, the action of reflecting ultraviolet rays in the upper storage area and the lower storage area is further increased, and the upper and lower shoes can be sterilized and deodorized over a wider range.

  In the footwear sterilization deodorization apparatus according to the present invention, the back wall portion, the door wall portion, the top wall portion, the bottom wall portion, and the pair of side wall portions are formed using a stainless steel plate. In addition, a structure that is provided outside so that the joint structure of the respective wall portions is not exposed to the accommodation region is preferably employed. In addition, various structures, such as welding, adhesion | attachment, a rivet, and a volt | bolt, can be employ | adopted as a junction structure of each wall part. The wall portions are combined with each other, the outer peripheral portion of each wall portion is fixed using a rivet, and the storage area is formed so that the rivet is not exposed to the storage area. In addition to obtaining corrosion resistance and strength, the adoption of a joint structure that is not exposed to the housing area can ensure the housing area more advantageously, improving usability, and discoloration burns caused by welding of the wall and the like. A reduction in the reflection effect of the mirror finish due to the exposure of the rivet is avoided, and further improvement of the sterilization and deodorizing effect based on the reflection of ultraviolet rays can be achieved.

  In the footwear sterilization deodorizing apparatus according to the present invention, the structure in which the partition member having the plurality of through holes is formed by punching a rectangular flat plate-shaped stainless steel plate is preferably employed. Is done. According to such a structure, the strength and corrosion resistance of the partition member can be advantageously ensured, and a relatively simple structure can be realized. In addition, by using a stainless steel plate, the surface of the partition member can be mirror-finished, etc., and the ultraviolet irradiation region can be made more uniform by reflecting ultraviolet rays more variously. It becomes possible.

  Moreover, in the footwear sterilization deodorization apparatus according to the present invention, each of the height, width, and depth in the inner dimensions of the accommodation area is 250 to 500 mm, and is installed in an individual room of the accommodation facility. A structure provided for personal use may be employed. According to such a structure, it is possible to advantageously install in an individual room of an accommodation facility such as a hotel or a ryokan by utilizing the fact that the entire structure is realized in a compact manner by accommodating the upper and lower shoes one by one. It is also possible for guests to sleep with both upper and lower shoes in the device and go to bed and complete the sterilization and deodorization treatment of the upper and lower shoes when waking up, thereby improving the cleanliness of the upper shoes of the accommodation facility. In addition, the guest can comfortably use underwear even after checkout, and an excellent service can be provided. In particular, by setting such a volume, it is possible to make the irradiation amount of ultraviolet rays substantially uniform over the whole while ensuring a sufficient storage area for upper and lower footwear for one person, and for footwear to be stored. On the other hand, the sterilization and deodorizing effect due to ultraviolet rays and photocatalytic action can be exerted evenly over the entire toes and the like.

  Further, the present invention relating to the sterilization and deodorization method of footwear is characterized by a rectangular box-like body provided with an open / close door, and a back wall portion, a door wall portion, and a ceiling wall that are spaced apart from each other on the inside. A storage region is defined by the portion, the bottom wall portion, and the pair of side wall portions, and a partition member having a plurality of through holes is disposed in an intermediate portion in the height direction of the storage region. An upper storage area is formed on the top wall portion side and a lower storage area is formed on the bottom wall side, and further, the back wall portion of the upper storage area and the lower storage area Ultraviolet irradiation tubes are arranged on the back wall part so that the upper part extends horizontally from the center, and the top wall part and the back wall part are each mirror-finished over the entire surface. Each of the pair of side wall portions and the door wall portion over the entire surface. Using a footwear sterilization deodorization apparatus in which a catalyst layer is formed, the upper footwear as the footwear is placed on the partition member in the footwear sterilization deodorization apparatus and is stored in the upper storage region, and the heel portion of the footwear is While facing the back wall portion, the toe portion of the upper footwear is directed to the door wall portion, and underwear as footwear is placed on the bottom wall portion in the sterilization deodorizing apparatus for footwear and stored in the lower storage area Then, after the heel portion of the underwear is directed to the back wall portion and the toe portion of the underwear is directed to the door wall portion, after the upper and underwear are accommodated in the accommodation area, the open / close door is closed. The housing area is shielded from the external space, and the ultraviolet irradiation tube in the upper housing area and the ultraviolet irradiation tube in the lower housing area are energized and emitted to simultaneously sterilize and remove the upper and lower shoes. Processing in the sterilization deodorization method of footwear to be.

  According to such a method of the present invention, as is clear from the description of the footwear sterilization deodorization apparatus according to the present invention described above, while suppressing damage caused by direct ultraviolet irradiation of the footwear, in a relatively short time, Excellent sterilization and deodorizing effects can be obtained.
