Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a deodorizer for deodorizing the internal air of a refrigerator, a cupboard or an airtight container, and more particularly to a deodorizer that can be attached to the side wall of a refrigerator or a container without taking up space. ..

[0002]

[Prior Art]

 When storing various foods in refrigerators, cupboards, or closed containers, it is widely practiced to add a deodorant to remove various odors emitted from the stored foods. As such a deodorant, activated carbon is crushed into particles and placed in a container made of synthetic resin, and a number of ventilation openings are provided at the top and sides of the container to allow contact with the outside air. There is. However, the granular activated carbon has a large average pore size for adsorption and has a large variation, and thus not only has a low adsorption rate and low odor holding power, but also has the drawback that the container itself occupies a bulky space.

On the other hand, an activated carbon mat in which activated carbon fibers, which have a higher adsorption rate and a higher odor retention than granular activated carbon, are mixed with glass short fibers to form a mat, have been put into practical use, and the activated carbon mat is breathable. A deodorizer contained in a bag is also proposed, for example, in Japanese Utility Model Publication No. 57-14221.

[0004]

[Problems to be solved by the device]

 This made it possible to provide a thin deodorizer that does not take up a lot of space, but when it is simply placed on a shelf, it must be leaned against the side wall or placed flat on the shelf. As a result, one side of the activated carbon mat comes into contact with the side wall and the shelf plate, so only the other side of the activated carbon mat comes into contact with the air, and there is little contact with the air in the refrigerator or shelf, and sufficient deodorization is achieved. However, the only solution to this problem is to hang it in the center of the cabinet or shelf, and the deodorizer becomes an obstacle when storing. Further, since the bag is covered so as to wrap around the outer peripheral surface of the activated carbon mat, only the air contacting the bag can be deodorized according to the flow of air such as convection, and the deodorization efficiency must be lowered.

Therefore, an object of the present invention is to provide a deodorizer having a thin deodorizer that uses an activated carbon sheet and at the same time having sufficient contact with the outside air to improve the deodorizing effect. ..

[0006]

[Means for Solving the Problems]

 The deodorizer of this invention has an activated carbon sheet formed by pressure-molding activated carbon fiber into a sheet shape, a bottom plate member made of paper or synthetic resin, and an outer peripheral portion having a height longer than the thickness of the activated carbon sheet. A front member having an upper surface portion integrally formed from one end of the outer peripheral portion and the other end portion of the outer peripheral portion adhered to the outer periphery of the bottom plate member, and the front member is permeable to air. It is made of non-woven fabric made of synthetic resin, and an activated carbon sheet is inserted into a space composed of a bottom plate member and a front member.

[0007]

[Action]

 According to the above configuration, air can be retained in the space between the bottom plate member and the front member, and the activated carbon sheet inserted into this space can be reliably contacted with air containing odor. At the same time, the entire deodorizer can be made thin. In addition, since the front member is made of non-woven fabric, its density, that is, the amount of air permeation can be easily set, and when the air in the refrigerator or the like is forcibly circulated by a fan or the like, and the air volume is strong, Adjustments such as increasing the density and increasing the residence time of air in the void can be made.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. The deodorizer 1 includes an activated carbon sheet 2 formed into a sheet shape by pressure-molding activated carbon fibers, and a bottom plate member 3 made of paper or synthetic resin. , A non-woven front member 4 made of, for example, 150 g / cm 2 of polypropylene fiber. A double-sided adhesive tape 5 is attached to the back surface of the bottom plate member 4. The front surface member 4 is an outer peripheral portion 6, an upper surface portion 7 integrally formed from one end portion of the outer peripheral portion 6, and a peripheral edge which is the other end portion of the outer peripheral portion 6 attached to the outer periphery of the bottom plate member 3. The height of the outer peripheral portion 6 is higher than the thickness of the activated carbon sheet 2. As a result, the bottom plate member 3 and the bottom plate member 3 form a space 9 for accommodating the activated carbon sheet 2. The front member 4 is thermoformed into a suitable shape, in this embodiment a pumpkin, as shown in FIG.

The activated carbon sheet 2 is obtained by sandwiching and pressing activated carbon fibers between two pulp fibers to form a sheet. For example, an activated carbon sheet sold under the trade name “Kractive” by Kuraray Co., Ltd. or an activated carbon sheet. It is called impregnated carbon in which fibers are impregnated with a chemical so that it can absorb odors that are difficult to be adsorbed by activated carbon. For example, the activated carbon sheet sold under the product name "TB Blasheet" by Kuraray Co., Ltd. is cut into a predetermined size. Use what you did. When the thickness of the activated carbon sheet 2 is 1.5 mm, for example, the height of the outer peripheral portion 6 of the front member 4 is set so that the distance between the bottom plate member 3 and the upper surface portion 7 of the front member 4 is about 15 mm. ..

When the front member 4 is used in a refrigerator or the like, the amount of air blown by a fan for stirring the cold air in the refrigerator is kept to 0.5 m / sec or less and the air in the void 9 comes into contact with the activated carbon sheet 2. The fiber density is adjusted by, for example, embossing 10 so as to secure the time of 0.5 seconds or more.

The double-sided adhesive tape 5 is coated with an adhesive whose adhesive strength is set so as to strengthen the adhesion with the bottom plate member 3 on the inner surface, and is removed when the outer surface is adhered to the side wall of a refrigerator or the like. Sometimes, tape with weak adhesive strength is used so that it can be removed without leaving adhesive residue.

When the deodorizer 1 configured in this way is installed in a refrigerator, the release tape (not shown) covering the outside of the double-sided adhesive tape 5 is peeled off, and the surface is attached to the side wall of the refrigerator shelf. You can fix it to. As a result, the deodorizer 1 is fixed in an upright position and does not take up much space. The odor-containing air in the refrigerator flows into the space 9 through the front member 4 and comes into contact with the activated carbon sheet 2 to adsorb the odor. Since the activated carbon fiber of the activated carbon sheet 2 is pressurized, the contact interval with the adjacent activated carbon fiber becomes narrow, and the odor adsorbed on the surface of the activated carbon fiber gradually moves to the new activated carbon fiber inside. .. Therefore, even if the air permeability of the central part of the activated carbon fiber decreases due to pressure, the odor gradually shifts to the internal activated carbon fiber, so that the adsorption performance does not decrease in a short time and the deodorization does not occur for a long time. The effect can be sustained. Further, since the non-woven fabric of the front member 4 is set to have an air flow rate of 0.5 m / sec or less, it can be retained in the void 9 for 0.5 sec or more and ensure contact with the activated carbon sheet 2. You can Furthermore, since the activated carbon sheet 2 is only inserted in the space 9, it is highly possible that the activated carbon sheet 2 leans diagonally when the deodorizer 1 is leaned against, but when it leans, both sides of the activated carbon sheet 2 come into contact with air. However, a further deodorizing effect can be exhibited.

In the above-mentioned embodiment, one activated carbon sheet 2 is put in the void 9, but a plurality of activated carbon sheets 2 may be laminated, and thus a deodorizer that can be used for a long period of time is provided. Can be provided. In addition, the activated carbon sheet 2 may be adhered and fixed to the bottom plate member 3 on one surface thereof. Further, the front member 4 is thermoformed in the shape of a pumpkin, but it is not limited to this, and a nonwoven fabric made of synthetic resin can be thermoformed in any shape, so that it can be formed according to the preference of the user. It can be shaped like this.

[0014]

[Effect of the device]

 As described above, the deodorizer of the present invention has a sheet-like activated carbon sheet, a bottom plate member made of paper or synthetic resin, and a space for accommodating the activated carbon sheet between the bottom plate member. The front part is made of breathable non-woven fabric and the outer periphery of the front part is set to a height longer than the thickness of the activated carbon sheet, and there is a space between the bottom plate part and the front part. Since the air is formed so that the air can be retained, the activated carbon sheet inserted therein can be surely brought into contact with the air containing the odor, and the deodorizer as a whole can be made thin. Since the front member is made of non-woven fabric, its density, that is, the amount of air permeation, can be easily set, and the air in the refrigerator or other refrigerator is forcibly circulated by a fan, etc. To increase the residence time of air in the void, or to reduce the density of the non-woven fabric when there is little air circulation inside, such as in a cupboard, so that even a slight air flow causes air to enter the void. Can be adjusted to fit.
