Description

[Detailed Description of the Invention] The present invention relates to a deodorizing device used in refrigerators and the like.

The deodorizing device used in conventional refrigerators uses activated carbon as an active ingredient, and its deodorizing power is to adsorb odors.At the beginning of use, it is efficiently adsorbed to the activated carbon surface and deodorized, but the stored activated carbon Since it is difficult to efficiently adsorb to the inside of the layer, the effectiveness gradually decreases as time passes, and the final state of effectiveness is unknown.

To counter this, people sometimes shake the deodorizer to stir up the activated carbon inside, or write the date of first use on the deodorizer to use it as a guide to the expiration date.

Additionally, deodorizing devices that use gel-like deodorizers are already on the market, but these also deodorize efficiently at the beginning of use, but as time passes, a reacted layer forms on the surface of the gel-like deodorizer. As a result, the deodorizing effect deteriorates, the active ingredients inside cannot be completely released, and the expiration date of the effect cannot be confirmed.

The present invention has been improved to avoid the various drawbacks of the above-mentioned known deodorizing devices, and it can continuously demonstrate good deodorizing efficiency and easily confirm the end of deodorizing power.
The present invention relates to a deodorizing device that can prevent leakage of deodorizing liquid due to falling, is clean and safe to use, and can be manufactured economically.

To explain the deodorizing device of the present invention with reference to an embodiment, a transparent or translucent cylindrical container 1 made of vinyl chloride resin or glass has a top surface 2 formed into a flat surface, and an outer periphery of an upper peripheral wall 3 that follows this. A protruding ring 4 is provided protrudingly, and a step portion 5 is provided or not provided following the lower end of the upper peripheral wall 3, and a male spiral strip 6 is provided on the outer periphery. 7 is formed at the lower part of the upper peripheral wall 3.

An aqueous transpiration deodorizing liquid 8, for example, a 0.5% stabilized chlorine dioxide aqueous solution, is housed in a cylindrical container 1, and a membrane, i.e., water repellent, is provided on the top surface 2 of the container 1, which has air permeability but does not allow aqueous liquid to pass through. The air permeable membrane 9 is adhered using a vinyl adhesive 10 to close the opening.

The water-repellent air permeable membrane 9 is, for example, a 0.2 mm thick sheet of porous tetrafluoroethylene resin manufactured by Sumitomo Electric Co., Ltd. (trade name: POREFLON), with perforations of around 5 μm, or a sheet manufactured by Tokuyama Soda Co., Ltd. water repellent NF
Sheet (polypropylene sheet approximately 0.25mm thick,
(with micropores of approximately 4 μm perforated on the entire surface) etc. are used.

Next, the press frame 11 has its upper top peripheral edge 12 widened to have an opening, or as shown in FIGS. The rods 14 or, as shown in FIG. 8, the vertical and horizontal support rods 13' and 14' are arranged in a lattice pattern, etc., so that fingertips, etc. cannot pass through the divided openings 15, and the openings are sufficiently wide. A recessed fitting groove 16 and a recessed groove 17 are provided on the inside of the side wall of the press frame 11 so as to be held in place, and are to be fitted into the projecting edge 4 of the upper circumferential wall 3 of the cylindrical container 1.

This pressing frame 11 is placed on the water-repellent gas-permeable membrane 9 adhered to the top surface 2 of the container 1, and pressed from above to fit the frame 11 into the upper circumferential wall 3 of the container 1. The outer peripheral edge of the air permeable membrane 9 is connected to the top surface 2 of the container 1 and the frame 1.
A shielding plate 20 in which a foamed vinyl chloride plate 18 is bonded between two vinyl chloride plates 19, 19 is placed on top of the shielding plate 20. Incidentally, the shielding plate 20 may be a single-piece vinyl chloride board.

The lid body 21 has a generally T-shaped hanging rod 22 protruding from the top of its upper cylinder part 23, has a large number of window holes 24 at the front and rear, and has a wide-diameter lower cylinder part continuous to the upper cylinder part 23. 25 is
The inner circumferential upper edge 26 is formed into a flat surface, and the inner circumferential upper edge 2
6 and the upper top periphery 12 of the pressing frame 11 press and hold the outer periphery of the shielding plate 20, and the outer periphery of the middle periphery wall 7 of the container 1 is attached to the lower inner periphery of the lower cylinder portion 25. A female spiral 27 to be screwed onto the spiral thread 6 is provided.

Then, a water-repellent air-permeable membrane 9 is adhered to the top surface 2 of the container 1 containing the aqueous evaporative deodorizing liquid 8,
The concave fitting grooves 16 and 17 of the side wall of the press frame 11 are fitted into the projecting edge 4 of the upper peripheral wall 3 of the container 1, and the outer peripheral edge of the water-repellent air-permeable membrane 9 is pressed against the top surface 2 of the container 1. Frame 11
The press frame 11 is attached to the cylindrical container 1 by being sandwiched between the lower surface of the upper top peripheral edge 12, and a shielding plate 20 is placed thereon to cover the opening 15 of the press frame 11 through which the fingertips do not pass. A T-shaped hanging rod 22 and a window hole 24 are provided in the upper cylinder part 23, and the lower cylinder part 25 is provided with a lid body 21 having a flat inner circumference upper edge 26 and a female spiral 27 on the lower inner circumference,
The lower cylinder part 25 is screwed into the middle peripheral wall 7 of the cylindrical container 1, and the outer peripheral edge of the shielding plate 20 is connected to the lower cylinder part 2.
5 inner peripheral upper edge 26 and the upper top peripheral edge 1 of the pressing frame 11
Attach it by pressing and holding it with 2.

When the device of the present invention is used, the lid 21 is removed, the shielding plate 20 is removed, and the device is placed at the place of use and used, or the device is hung with only the lid 21 attached.

When the deodorizing device of this invention is stored in a refrigerator etc.,
Chlorine dioxide, which evaporates with water, is removed by water-repellent air permeable membrane 9.
It diffuses into the refrigerator through the water, oxidizes when it comes into contact with malodorous components such as mercaptan, and becomes odorless.

The deodorizing device of the present invention has a container 1 with a water-repellent air-permeable membrane 9.
Since the aqueous evaporative deodorizing liquid 8 is sealed and stored inside the container, even if the container is accidentally tipped over during use, the water-repellent air-permeable membrane 9 is water-repellent and its micropores are Since the pores are small enough to allow ventilation, the transpirable deodorizing liquid 8 will not leak through the pores.

Therefore, the deodorizing device of the present invention can be used cleanly and safely without contaminating other objects due to liquid leakage even when it falls down.

Since the device of the present invention uses an aqueous solution of chlorine dioxide as the evaporative deodorizing liquid 8, the deodorizing component can freely flow and diffuse, and unlike gel-based deodorizing agents, a reacted layer is formed on the surface during use. Therefore, a good deodorizing effect can always be continuously exhibited without reducing the deodorizing effect.

In addition, the materials and manufacturing steps required for gelation using agar and gelatin can be omitted, making it possible to provide a deodorizing device that is easy to manufacture and inexpensive.

Furthermore, since the aqueous transpiration deodorizing liquid 8 of the present invention is used by storing it in a transparent or translucent container 1, the amount of transpiration and consumption of the deodorizing liquid 8 can be observed at a glance from the outside, and the final stage of deodorizing power, i.e. The completion of transpiration of the deodorizing liquid can be easily and accurately confirmed.

Furthermore, even if the present invention is used with the lid 21 removed, the press frame 11 does not allow the water-repellent air-permeable membrane 9 to be attached to the upper top edge 1 of the container 1.
2, and the frame 11 is fitted and fixed to the protrusion 4 of the upper circumferential wall 3 of the container 1, so that the water-repellent air-permeable membrane 9 will not come off from the container 1 if the container 1 accidentally falls over. You can always use it with confidence.

Furthermore, if the pressing frame 11 is configured to be opened to an extent that does not allow the fingertip to pass through, the water-repellent air-permeable membrane 9 can be accidentally opened during handling.
No need to worry about damaging it.

Since the deodorizing device of the present invention has the various functions and effects described above, it can be used not only in refrigerators but also in trash cans and other places that emit odors.
