Utility Model Registration No. 3119662

  However, the deodorizing apparatus of the above document has a drawback that the titanium dioxide on the surface side of the block piece peels off due to the rubbing of the block pieces inside the bag body, and the deodorizing effect is reduced. The titanium dioxide impregnated inside has a disadvantage that the function as a photocatalyst is lowered and the deodorizing effect is hardly exhibited.

  An object of the present invention is to provide a deodorizing device that performs deodorization using titanium dioxide that functions as a photocatalyst, and that exhibits a high deodorizing effect continuously.

  In order to solve the above-mentioned problem, a deodorizing device for deodorizing using titanium dioxide functioning as a photocatalyst, a plurality of sheet pieces impregnated or coated with a paint containing titanium dioxide, And at least a part of the plurality of sheet pieces is impregnated with the paint so that the paint is exposed on one side or both sides. It has a coated sheet piece main body and a cover that covers and covers the exposed surface, which is the surface of the sheet piece main body where the paint is exposed, and the sheet piece main body or the cover has air permeability and light permeability. It is characterized by.

  The paint may contain a component that exhibits a heat insulating effect.

  The bag body may be formed from a mesh-like flexible and deformable cloth.

  The bag body may be formed into a pipe shape that can be deformed flexibly.

  A binding tool may be provided on the pipe-shaped end side of the bag body.

  The binding tool may be a band or string that can be flexibly deformed.

  The belt-shaped body may be provided on both ends of the bag-shaped pipe.

  The sheet piece main body may be made of woven fabric, non-woven fabric, felt or Japanese paper.

  One or both sides of the sheet piece impregnated or coated with a paint containing titanium dioxide is an exposed surface from which the paint is exposed, and this exposed surface is protected by a cover to prevent the paint from peeling off. Since the air contact with the exposed surface and the light irradiation are ensured by the sheet piece main body or the cover having air permeability and light permeability, it is possible to continuously exert a high deodorizing effect.

It is a top view explaining the usage example of the deodorizing instrument to which this invention is applied. It is a top view of the deodorizing instrument of FIG. It is a side view of the deodorizing instrument of FIG. It is AA sectional drawing of FIG. It is sectional drawing of a sheet piece. It is a side view which shows an example of the formation means of a sheet piece. (A), (B) is sectional drawing which shows the structure of the modification of a deformation sheet, respectively.

  FIG. 1 is a plan view for explaining an example of use of a deodorizing apparatus to which the present invention is applied. The deodorizing instrument 1 to which the present invention is applied is set at a place where a space to be deodorized touches. For example, in the example shown in FIG. 1, the deodorizing instrument 1 is installed on the air intake side (in other words, in the middle of the air flow path or circulation path) of the electric fan 51 through which air flows, and the room (space). The whole air is deodorized.

  2 and 3 are a plan view and a side view of the deodorizing apparatus of FIG. 1, and FIG. 4 is a cross-sectional view taken along line AA of FIG. The deodorizing device 1 includes a bag body 2 formed into a pipe shape that can be changed flexibly, a large number of sheet pieces 3 accommodated in the bag body 2, and pipe ends of the bag body 2. The provided binding tools 4 and 4 are provided.

  The said bag body 2 is comprised from the mesh fabric (mesh-like cloth) which has sufficient air permeability and light permeability, and can be changed flexibly. Explaining in detail, this mesh fabric is formed into a pipe shape by folding the square cloth into two at the center in the short axis direction, folding back the long side parts inward, and stitching them together. In this state, all the sheet pieces 3 are inserted and accommodated from the other open end, and then the other end is sewn and closed, and the sheet inside the bag body 2 is closed. Prevent the piece 3 from leaking out.

  Since the mesh fabric can be changed flexibly, the bag body 2 filled with a large number of sheet pieces 3 can also be changed flexibly. For example, the middle part is bent to form a dogleg shape, the pipe-shaped end parts are bound together by binding tools 4 and 4 to form a donut shape, or as shown in FIG. In addition, it is possible to make the whole part into a U shape by bending two places in the middle.

  The said binding tool 4 is a strip | belt-shaped body or string-shaped body (in the example shown in figure, a strip-shaped body) which can be changed flexibly. With this binding tool 4, the pipe-shaped end portion side of the bag body 2 is bound and fixed to other parts (for example, the electric fan 51 shown in FIG. 1), or both ends of the pipe-shaped end portion of the bag body 2 are fixed. Can be bound together.

  FIG. 5 is a cross-sectional view of the sheet piece. The sheet piece 3 has a rectangular sheet-like base material (sheet piece main body) 6 that can be deformed flexibly, and a cover 7 that covers at least one side of the base material 6.

  The material constituting the base material 6 includes a woven fabric made by weaving a fiber twisted into a yarn, a non-woven fabric intertwined into a sheet without weaving the fibers, animal hair and chemical fibers thinly A sheet-like felt made by compressing into a plate shape, a Japanese paper made into a thin sheet while entwining long fibers such as plants, etc. are used. The base material 6 made of these materials is bendable and stretchable, is not easily damaged, has sufficient air permeability, water permeability and light permeability, and is easy to wash.

  By applying or impregnating a liquid paint having a deodorizing effect and a heat insulating effect on one side or both sides of the base material 6, and then drying and solidifying, the paint was contained on the one side or both sides. The containing layer 8 is formed. The surface of the substrate 6 on which the containing layer 8 is formed becomes an exposed surface 6a where the active ingredient contained in the paint is exposed.

  This paint is a white solution obtained by blending sodium aluminosilicate glass, a pigment, a resin emulsion, a dispersant, an adhesive, and the like, adding water, and stirring and mixing.

  The aluminosilicate soda glass has a hollow bead structure with a particle size of 10 to 50 μm and has a heat insulating effect. The content of this aluminosilicate glass is 10 to 20% by weight of the total weight of the paint. By the way, when the content of sodium aluminosilicate glass is less than 10% by weight, the heat insulating performance is lowered, and when it exceeds 20% by weight, the adhesive force to the substrate 6 is lowered. Is set.

  The pigment is made of white titanium dioxide that functions as a photocatalyst that reflects light and exhibits a deodorizing effect.

  The resin emulsion is a water-soluble acrylic emulsion resin, and the dispersant is for uniform mixing of the component materials consisting of sodium aluminosilicate glass, pigment, and resin emulsion, and the adhesive is uniform. This is to suppress separation and precipitation of the mixed component materials.

  The liquid coating material in which these are mixed is uniformly applied to the exposed surface 6a of the substrate 6 by spraying from a nozzle or the like, and then dried, so that the coating material is impregnated to a predetermined depth from the exposed surface 6a, and the above-mentioned containing layer 8 is formed. And on this exposed surface 6a, an aluminosilicate sodium glass which is an effective component having a heat insulating function and titanium dioxide which is an effective component having a deodorizing effect are exposed as effective components.

  That is, the paint is a heat insulating paint and a deodorant paint, and is applied to and impregnated on the surface of the base material 6 to form the heat insulating layer 8 that is resistant to bending and has high durability on the surface layer of the base material 6. . For this reason, the base material 6 is also comprised from the above materials so that a heat insulation paint can be impregnated.

  Note that the base material 6 may be impregnated with the paint by immersing the base material 6 in the liquid paint. In addition, this coating material may be applied only to the surface of the substrate 6. In this case, since it is not necessary to impregnate the base material 6 with the paint, the base material 6 does not need to ensure permeability to the liquid, and wood chips and the like can be selected. improves.

  The cover 7 is composed of a woven fabric or a non-woven fabric that ensures air permeability, water permeability and light permeability. The cover 7 covers and protects the exposed surface 6 a of the base material 6.

  The fixing means for fixing the cover 7 to the base material 6 will be further described. The cover 7 is bonded or stitched to the base material 6 in a state where the cover 7 is in contact with the entire exposed surface 6a (more specifically, in close contact). doing.

  Specifically, the cover 7 is impregnated with hot melt such as urethane adhesive, and this is exposed to an exposed surface 6a of the substrate 6 with a high-temperature (more specifically, about 120 to 160 ° C.) iron or a metal plate. Then, the cover 7 is bonded to the base material 6 by being pressure-bonded while being heated (hot pressing), or the base material 6 and the cover 7 are stitched together in a staggered pattern by a sewing machine or the like. Further, the cover 7 may be attached to the substrate 6 by a combination of adhesion and stitching.

  FIG. 6 is a side view showing an example of sheet piece forming means. As shown in the figure, a plurality of sheet pieces 3 may be formed by chopping a shredding sheet 9 having a cross-sectional structure similar to that of the sheet piece 3 into a lattice shape. Moreover, after cutting and forming a required shape from this shredding sheet 9, the sheet piece 3 may be shredded from the rest. This can reduce waste.

  According to the deodorizing instrument 1 configured as described above, the pair of binding tools 4 and 4 can be freely installed in the middle of the air flow path.

  Moreover, the pipe-shaped deodorizing instrument 1 which can be changed flexibly can be installed in various places, and is highly versatile.

  Moreover, the light from the outside of the bag body 2 is irradiated inside the bag body 2 due to the translucency of the mesh fabric constituting the bag body 2, passes through the base material 6 and the cover 7, and includes the exposed surface 6 a and the contained light. It reaches layer 8 and is deodorized by the function of titanium dioxide as a photocatalyst. The exchange of the deodorized air on the exposed surface 6a side and the non-deodorized air outside the bag body 2 is performed through the mesh fabric of the bag body 2 having air permeability and the base material 6 and the cover 7. Done.

  Furthermore, the action of titanium dioxide as a photocatalyst is promoted by the temperature rise due to the heat insulating effect of the paint, and the deodorizing effect is further improved.

  Moreover, since the containing layer 8 and the exposed surface 6a of the sheet piece 3 are covered and protected by the cover 7, an active ingredient (for example, titanium dioxide or aluminosilicate soda glass caused by the friction between the sheet pieces 3). ) From the exposed surface 6a is prevented, and the above-described temperature rise effect is further enhanced.

  By the way, the fine sodium aluminosilicate glass is laminated innumerably and is also linked in a plane along the heat insulating surface, so that the heat reaching the containing layer 8 is reflected by the surface of the sodium aluminosilicate glass. As a result, permeation is suppressed, and planar convection heat and conduction heat along the containing layer 8 are also suppressed by the hollow portion of the aluminosilicate sodium glass.

  In addition, since it is only necessary to ensure air permeability and translucency in the space on the exposed surface 6a side where the active ingredient is exposed, air permeability is ensured in at least one of the base material 6 and the cover 7, and the base material 6 and the cover 7 are provided. Translucency should just be ensured in at least one of these.

  In addition, the sheet pieces 3 are accommodated in the bag body 2 in various postures. However, in the illustrated example, the sheet pieces 3 may be accommodated in a stacked state so as to increase the filling amount.

  Next, differences from the above-described example will be described with reference to FIG.

  FIGS. 7A and 7B are cross-sectional views showing configurations of modified examples of the deformable sheet, respectively. In the example shown in FIG. 5A, a plurality of base materials 6 on which the content layer 8 is formed are stacked with the surface on the content layer 8 side facing in the same direction, and the other base materials 6 are not overlapped and exposed. The exposed surface 6 a is covered with a cover 7.

  In the example shown in FIG. 5B, the entire surface of the substrate 6 is impregnated with the coating material to form exposed surfaces 6a on both sides, and each exposed surface 6a is covered with a cover 7 for protection.
