Further, when the stored item (stored item) dries, an odor is generated and the air may be contaminated. For example, when an article used in a hospital or a nursing facility, a pet article, a shoe or an exercise tool that sucks sweat is dried, an odor component is scattered and pollutes the air.
For this reason, in addition to air conditioning equipment such as an air conditioner, there are devices that improve the environment, such as various types of air purifiers and deodorizing sterilizers. In addition to these devices, there is a drying device for drying a damp thing.

In order to remove airborne particles such as cigarette smoke, an air cleaner with a built-in filter is used. However, in this filter-type air purifier, the odorous component gas (hazardous gas) could not be removed suitably.
As a method for removing harmful gases, there is an afterburner method in which fuel is burned to burn off harmful substances. This has the problem of consuming very much fuel. There is also a method using an adsorbent such as activated carbon, but it requires labor and cost for maintenance management.

On the other hand, an oxidation catalyst type deodorizing and sterilizing apparatus that efficiently deodorizes and sterilizes by a heating effect and a catalytic effect has been proposed (see Patent Document 1). In this deodorizing and sterilizing apparatus, a contaminated air purifying unit (deodorizing and sterilizing unit) deodorized by an oxidation catalyst system and a heat exchanging unit are arranged in series. And it is provided so that clean air may be discharged indoors and air may be circulated indoors. According to this deodorizing and sterilizing apparatus, it is possible to efficiently perform deodorizing and sterilizing the room where the apparatus is installed. However, this device does not provide a closed and high purification space, and is not intended for storing or managing stored items.
Moreover, a deodorizing and sterilizing apparatus for boots having a heat drying function and an ozone generator has been proposed (see Patent Document 2). This device is deodorized by adsorbent and activated carbon. In addition, it is simply heat-dried or steam sterilized, and is a device exclusively for boots in temperature management and the like.

Reference numeral 12 denotes an outer case, and an opening / closing portion 13 (see FIG. 2) is provided on the front surface. The opening / closing portion 13 is, for example, a door that opens on both sides so that large objects can be easily taken in and out. It consists of

Reference numeral 15 denotes a first introduction flow path, which is a flow path for introducing the air to be treated from the closed chamber 10 to the deodorizing and sterilizing unit 20. In the figure, the air flow is indicated by solid arrows.
Reference numeral 26 denotes a first supply flow path, which is a flow path for supplying clean air purified together with the heating discharged from the deodorizing and sterilizing unit 20 to the closed chamber 10. In the figure, the air flow is indicated by solid arrows.
The first circulating air flow path is constituted by the first introduction flow path 15 and the first supply flow path 26 described above. In addition, each flow path should just be a channel | path through which air can pass suitably, and is not limited to a duct like this form.

Reference numeral 17 denotes a second introduction flow path, which is a flow path for introducing air from the closed chamber 10 to the heat exchanger 30. In the figure, the flow of air is indicated by a dashed-dotted arrow.
Reference numeral 40 denotes a second supply channel, which is a channel for supplying clean air that has passed through the heat exchanger 30 and has been cooled to the closed chamber. In the figure, the flow of air is indicated by a dashed-dotted arrow.
The second circulating air flow path is configured by the second introduction flow path 17 and the second supply flow path 40 described above. In addition, each flow path should just be a channel | path through which air can pass suitably, and is not limited to a duct like this form.

By using the oxidation catalyst type deodorizing and sterilizing unit 20 as described above, the deodorizing and sterilization in the closed chamber 10 can be performed preferably and efficiently. Since the deodorizing and sterilization of air is suitably performed, an article to be stored can be properly stored. Since air is circulated, it is possible to prevent odors and germs from leaking outside the apparatus and improve the environment of the installation location of the apparatus.
In the deodorizing and sterilizing unit 20, the air is purified and heated, and the heated air is directly supplied to the closed chamber 10 through the first supply channel 26. For this reason, it can heat suitably so that a storage thing (storage thing) may be dried. Accordingly, it is possible to promote drying of the storage object.
Moreover, since air is circulated, purification efficiency can be improved. This is to repeat further cleaning of the cleaned air. Moreover, there is little energy loss and energy consumption can be reduced.

Reference numeral 16 denotes a first blower, which sends the air to be treated from the first introduction flow path 15 to the deodorization sterilization section 20 and clean air from the deodorization sterilization section 20 to the closed chamber 10 via the first supply flow path 26. To discharge. The first blower 16 generates an air flow that circulates between the closed chamber 10 and the deodorizing and sterilizing unit 20.
Reference numeral 27 denotes a second blower, which sends air from the closed chamber 10 to the heat exchanger 30 via the second introduction flow path 17 and closes from the heat exchanger 30 via the second supply flow path 40. Clean air is discharged into the chamber 10. The second blower 27 is disposed in each of the pair of heat exchangers 30. In this embodiment, the heat exchanger 30 is connected and arranged so as to blow air to the inlet chamber 31 that introduces air at the top of the heat exchanger 30. An air flow that circulates between the closed chamber 10 and the heat exchanger 30 is generated by the second blower 27.
As these blowers, sirocco fans are used, but other blowers may be used as long as a circulating air flow can be generated. Moreover, the arrangement | positioning position and installation number of an air blower are not limited to this, What is necessary is just to set so that a circulating airflow can be generated appropriately.

Reference numeral 41 denotes a rectifying chamber, which is a portion where the first supply channel 26 and the second supply channel 40 are merged and integrated, and the circulating air is uniformly supplied to the entire closed chamber 10 from below. In order to be able to do so, it is divided and provided by the baffle plate 42 under the closed room 10. As shown in FIG. 2, the rectifying plate 42 is formed in a corrugated plate shape, and a large number of vent holes 47 are provided. As a result, the surface area is increased to reduce the airflow resistance, and the air flow can be suitably uniformized.
An introduction port 11 from the closed chamber 10 to the first introduction flow path 15 is provided in the upper portion of the closed chamber 10.
By providing the air flow path in this way, air can be suitably sent from the lower side to the upper side in the closed chamber 10 without countering the rising property of the heated air. Since the air flow can be made uniform, deodorization efficiency, sterilization efficiency (purification efficiency), and drying efficiency can be increased. Moreover, it is possible to prevent bacteria and the like from being sedimented, and to improve sterilization efficiency and deodorization efficiency.

Reference numeral 60 denotes a blower with a heater. In addition to heating the air to be treated by the deodorizing and sterilizing unit 20 in order to dry the storage object more effectively, the air sucked from the closed chamber 10 is heated to the closed chamber 10. It is provided as a structure of the returning air heating circulation means. In the figure, the air flow is indicated by white arrows.
Reference numeral 61 denotes an air inlet, which serves as an inlet for introducing air from the closed chamber 10 into the fan 60 with a heater. It opens to the partition with the closed chamber 10 of the cross wind generating chamber 55 described later. Further, the rectifying chamber 41 described above also serves as a flow path to the closed chamber 10 of the air heating and circulation means. According to this, air can be heated and circulated suitably, and the stored object can be shortened. It can be dried efficiently in time. Of course, the air heating and circulation means need not be operated when a high drying capacity is not required. For example, when the circulating air is heated to 50 ° C. and the relative humidity becomes 20% or less, control such as stopping the operation may be performed.

As shown in FIGS. 1 and 3, the heat exchanger 30 is formed so that heat is exchanged between clean air flowing from the upper side to the lower side and outside air flowing from the lower side to the upper side. In the figure, the flow of clean air is indicated by a one-dot chain line, and the flow of outside air is indicated by a two-dot chain line. As shown in FIGS. 1 and 2, inlets 18 from the closed chamber 10 to the second introduction flow path 17 are provided on the left and right sides of the upper portion of the closed chamber 10.
Further, the outside air is blown by a cooling blower 39 provided at the lower portion of the heat exchanger 30. In this embodiment, an axial fan is used as the cooling blower 39, but other blower means may be used.

Thus, the heated clean air can be suitably cooled by flowing clean air and outside air from opposite directions. Thereby, a to-be-stored object can be stored suitably, without raising the temperature in the closed chamber 10. FIG. And when cooling the air which was heated and contained much moisture, the water | moisture content in air can be aggregated and a water droplet can be generated and dehumidified. For this reason, circulating air can be dried and drying of a storage thing can be accelerated suitably. Further, by sucking outside air at the lower part and opening it at the upper part, it is possible to prevent a situation in which fine particles containing bacteria that are likely to settle and accumulate on the floor are scattered again.
As a heat exchange method, water cooling, a refrigerator, or the like can be used, but the manufacturing cost increases.
Reference numeral 45 denotes a drain which serves as a discharge port for discharging water droplets generated by cooling and agglomeration of moisture in the air.

Reference numeral 50 denotes a cross wind generating unit that generates a cross wind air flow in a substantially horizontal direction in the closed chamber 10. In the figure, the air flow is indicated by dotted arrows. As shown in FIG. 5, the cross wind generator 50 of this embodiment is provided on one side of the closed chamber 10. 51 is a blower for cross wind, and is disposed in a discharge port 52 (see FIG. 1) that is an opening communicating with the closed chamber 10 in the cross wind generation chamber 55. For example, an axial fan is used as the blower 51 for cross wind, and air is discharged in the horizontal direction. Reference numeral 53 denotes an inlet, which is an opening through which the cross wind generating chamber 55 and the closed chamber 10 communicate. According to this, as shown in FIG. 5, the air flow is reversed in the cross wind generation chamber 55 and is also substantially reversed in the closed chamber 10, thereby generating a substantially horizontal cross wind air flow. .
According to this cross wind generation part 50, the air in a closed room can be suitably stirred with a cross wind. For this reason, deodorizing efficiency, sterilization efficiency (purification efficiency), and drying efficiency can be improved. Moreover, by providing in one side part, a moderate airflow can be generated and it can stir efficiently.

Next, the detail of a structure of each part is demonstrated.
First, the deodorizing and sterilizing unit 20 will be described.
Reference numeral 22 denotes a heating unit that heats the air to be treated sent by the first blower 16.
Reference numeral 24 denotes an oxidation catalyst unit, which is provided downstream of the heating unit 22 and deodorizes the heated contaminated air by the action of the catalyst.
The heating unit 22 and the oxidation catalyst unit 24 arranged in triplicate at intervals are provided as a set, and a deodorizing and sterilizing unit 20 for cleaning contaminated air is configured.
Reference numeral 21 denotes a deodorizing and sterilizing part case, which is a casing that houses the heating part 22 and the oxidation catalyst part 24. Moreover, 21a is a heat insulating material (refer FIG. 2).
In addition, when high deodorizing sterilization performance is requested | required, it can respond by arranging the heating part 22 and the oxidation catalyst 24 suitably, and arrange | positioning in multiple steps.

In the heating unit 22 of this embodiment, the contaminated air introduced into the deodorizing apparatus is set to be heated to about 280 ° C to 330 ° C.
Moreover, the heating part 22 of this embodiment has a form in which a heater wire made of a spirally wound nichrome wire or the like is spirally wound around the outer periphery of a bobbin 23 formed of a ceramic body. The bobbin 23 around which the heater wire is wound is fixed horizontally in the deodorizing and sterilizing case 21 so that the axis extends in the depth direction on the drawing of FIG. Therefore, the contaminated air to be treated is heated to a predetermined temperature while passing through the space above and below the bobbin 23 in the deodorizing and sterilizing unit case 21. Note that the temperature of the heater wire itself has reached a higher temperature, which also decomposes odorous components, and bacteria and viruses present in the air are heat sterilized.
The heating unit 22 is not limited to this embodiment as long as the contaminated air can be heated to a predetermined temperature. For example, a heater device (seeds heater) or the like having a thermostat function can be used.

The oxidation catalyst unit 24 deodorizes the contaminated air heated by the heating unit 22 by the action of the oxidation catalyst. In the present embodiment, the catalyst body 25 is configured by a catalyst formed on a ceramic body formed in a block shape.
The catalyst block 25 is formed with a honeycomb-shaped ceramic body having a large number of rectangular holes penetrating in the longitudinal direction of the deodorizing and sterilizing part case 21 (left and right in the drawing of FIG. 1). Specifically, γ alumina is applied to a carrier (ceramic body) made of a ceramic such as porous cordierite, and a catalyst such as platinum, palladium, rhodium, etc. is dispersed and coated on the surface.
In addition, as the oxidation catalyst part 24, instead of a ceramic body, a metal wire-like carrier such as an aluminum alloy coated with a catalyst dispersed in the same manner may be used. Alternatively, a porous ceramic support having a gas permeability and a catalyst supported thereon may be used.

Next, the heat exchanger 30 will be described.
As shown in FIG. 3, the heat exchanger 30 includes a heat exchanger case 33 and a plurality of cylinders 35 that are included in the case 33 and that have heat-radiating fins on the outside and heat-absorbing fins on the inside. And is formed from. In this embodiment, three cylindrical bodies 35 that are opened in the vertical direction are arranged in parallel in each of the pair of heat exchangers 30 and 30.
The cylinder 35 is connected to each air flow path so that outside air passes through the outside 35a and clean air passes through the inside 35b.
By providing the heat exchanger 30 in this way, clean air can be suitably cooled and supplied into the closed chamber 10.

  Hereinafter, an example of the best mode according to the cylindrical body 35 of the heat exchanger 30 of the present invention will be described in detail with reference to the accompanying drawings. FIG. 6 is a front view showing the cylindrical body 35 of the present invention. FIG. 7 is an explanatory view of the fin arrangement of the cylindrical body 35 in a plan view and a sectional view. FIGS. 8 and 9 explain the arrangement of fins adjacent to the fin of FIG. It is explanatory drawing. FIG. 10 is an enlarged view illustrating the lower left corner of FIG. 9 as an enlarged cross section.

Reference numeral 36 denotes a cylindrical material, which is formed of a metal material into a rectangular cylindrical shape. The cross-sectional shape is a rectangular frame. As shown in FIGS. 6 to 9, 37 a, 38 a, and 38 c are fins for heat exchange, and are formed by being formed of a metal material on the outside 36 a of the cylindrical material 36. These fins 37a, 38a, and 38c for heat exchange have a shape that extends from each side of the cylindrical member 36 so as to project in all directions. Further, as shown in FIGS. 7 to 9, heat exchange fins 37 b and 37 b made of a metal material are also provided in the inside 36 b of the cylindrical member 36.
Here, the metal material is not particularly limited as long as it is a material having a higher thermal conductivity than other materials such as a resin material and has a certain strength as a structural material. For example, an aluminum material, a stainless steel material, a steel material, a copper material, or the like may be selectively used as appropriate.

As shown in FIGS. 7 to 9, the heat exchange fins 37 a and 37 b are formed by a first metal plate 37. On the other hand, the heat exchange fins 38 a, 38 b, 38 c are formed by the second metal plate 38.
The metal plate members 37 and 38 are provided at predetermined positions by being inserted into and fixed to the slits 39 provided on the side walls 36c of the cylindrical member 36. The tubular member 36 and the metal plate members 37 and 38 can be appropriately fixed with a predetermined strength obtained by a fixing means such as spot welding.
The slit 39 is formed in a through hole shape by press punching or the like. The slit 39 is formed with a predetermined clearance with respect to the thickness and width of the metal plate members 37 and 38 so that the metal plate members 37 and 38 can be fitted easily and easily.

As shown in FIG. 10, the space between the slit 39 and the metal plates 37 and 38 is hermetically sealed by the coating 70. The coating 70 can be formed by an appropriate coating material (heat resistant paint) or plating. According to the film 70 formed of the heat resistant paint or the like, the heat resistant paint or the like can be suitably and easily hermetically sealed by entering the gap. In the case of only airtightness, the coating film 70 may be formed only on the outer surface only in the slit 39 portion into which the metal plate-like bodies 37 and 38 are fitted.
According to this, the leak between the inner part 36b and the outer part 36a of the cylindrical member 36 is prevented, and the deodorizing sterilization performance and the heat exchange efficiency can be improved.
Moreover, about the exterior of the cylinder 35, you may form the film containing a carbon nanotube in part or the whole surface of the surface including the radiation fin (fin 37a, 38a, 38c for heat exchange). For example, carbon nanotubes may be mixed with a paint and applied. According to this, heat exchange efficiency improves simultaneously with airtightness, and the heat exchanger can be downsized.

Further, as shown in FIGS. 7 to 10, the metal plate-like bodies 37 and 38 are provided with step portions 37 e and 37 e as stopper shapes so as to prevent them from being inserted into a predetermined dimension or more and fix them appropriately. Is formed.
The second metal plate-like body 38 has a shape extending through the inside 36b of the cylindrical member 36 formed in a rectangular cross section from one outer surface side to the opposite outer surface side. That is, it is formed so as to penetrate the opposing side walls 36c, 36c. On the other hand, the first metal plate 37 has a shape protruding into the interior 36b of the cylindrical member 36 to the extent that it does not interfere with the second metal plate 38 (FIGS. 8 and 9). reference).

In the cylinder 35 shown in FIG. 6, fins for heat exchange are provided in a plurality of (many) stages in the longitudinal axis direction of the cylinder 35. In more detail, the first metal plate 37 includes a part (see FIG. 7) that constitutes one step of the fins in a set of four pieces, two pieces of the first metal plate 37 and the second plate. A portion (see FIG. 8 and FIG. 9) is provided, in which one piece of the metal plate-like body 38 constitutes one step of the fin. In the configuration example of FIG. 6, the fin stage shown in FIG. 8 or FIG. 9 is inserted one stage after the fin stage shown in FIG. 7 continues.
The reason why a number of steps not using the second metal plate-like body 38 is provided is to reduce the ventilation resistance. The second metal plate 38 crosses the inside 36b of the cylindrical member 36, and is arranged to disturb the air flow and increase the heat transfer efficiency. However, it also acts to increase the ventilation resistance and reduce the processing air volume. For this reason, when it is desired to reduce the ventilation resistance in accordance with the use conditions, it is only necessary to install a number of stages not using the second metal plate 38 as appropriate, as in this embodiment.
As shown in FIGS. 8 and 9, a portion in which two sheets of the first metal plate 37 and one sheet of the second metal plate 38 form one set of fins is as follows. The arrangement is shifted by 90 ° for each stage. Thereby, air can pass through the inside 36b of the cylindrical member 36 without deviation, and the heat exchange performance can be improved.

Further, as shown in FIG. 6, the metal plate bodies 37 and 38 are fixed in a state of being inclined in the longitudinal axis direction of the cylindrical member 36. This is the same in all of the metal plate-like bodies 37 and 38 fixed to the side surfaces of the cylindrical member 36.
The reason for the inclination is to obtain a larger surface area within a predetermined volume and to improve the heat exchange performance by complicating the air flow. Moreover, it is also for suppressing the raise of the ventilation resistance in that case, and blowing efficiently.
Furthermore, in order to improve the heat exchange performance, the radiating fins (heat exchange fins 37a, 38a, 38c) are formed with slit-shaped cut portions 37f, 38f on the outer edges thereof. The same applies to the endothermic fins (heat exchange fins 37b, 38b), but each fin 37a, 37b, 38a, 38b, 38c has an appropriate slit shape, rectangular shape, or circle shape to improve heat exchange performance. You may provide through-holes, such as a shape.
In order to reduce the airflow resistance, for example, as shown in FIG. 9, a circular hole 38g may be provided in the inner heat exchange fin 38b.

  Further, as shown in FIGS. 8 to 10, the inner corner portion of the cylindrical member 36 and surrounded by the first metal plate 37 (37b) and the second metal plate 38 (38b). Is a rectangular empty space 43. This empty space 43 is formed over the entire length of the tubular member 36 of the heat exchanger. Further, it is formed at each of the four inner corners of the cylindrical member 36. Due to the presence of the empty space 43, an air flow in the longitudinal direction of the tubular member 36 is generated at each inner corner. As a result, air agitation is suitably performed in a well-balanced manner, and heat exchange performance can be improved.
