Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a moisturizing / deodorizing device that is placed in a refrigerator or the like to exert deodorizing and humidifying functions.

[0002]

[Prior art]

 There are various methods for storing food, but the low temperature storage method is one of the excellent methods. This is because the growth of microorganisms and chemical reactions can be suppressed by low temperatures. Because of this, refrigerators have become popular in households.

By the way, odors from various foods are mixed in the refrigerator to give off a strange odor. Therefore, it was necessary to deodorize the inside of the refrigerator. On the other hand, the inside of the refrigerator is kept in a non-steady state in which the related humidity rises and the temperature drops below the dew point as water is gradually removed as it cools. Under such a condition, fresh vegetables, fish and the like were dried, withered and the food surface was wilted, and the damage was accelerated. Therefore, in order to make full use of the low temperature storage, it is also necessary to perform a moisturizing operation inside the storage.

For removing the odor, a method utilizing an adsorption principle such as an activated carbon adsorbent or a method of installing an ozone generator in a refrigerator has been conventionally used. In addition, the moisturizing measures have been based on the method of soaking non-woven fabric, water-absorbent polymer, etc. in water and placing them in a refrigerator, or by mechanically humidifying.

[0005]

[Problems to be solved by the device]

 However, simply arranging water-absorbing polymers with water as a moisturizing measure had a problem in that the odor in the refrigerator was dissolved in the water and a bad odor drifted when it evaporated. Also, the method of mechanically humidifying is too large and too expensive for home use. On the other hand, as an odor remover, one using an adsorbent is widely used in households, but there has never been an odor remover that has a moisturizing function as a placement type.

The present invention solves the above problems, and an object of the present invention is to provide a simple installation type moisturizing deodorizer which integrates a deodorant and a water retention agent, mainly for household refrigerators.

[0007]

[Means for Solving the Problems]

 In the moisturizing deodorizer of the present invention, the accommodating chamber of the water retaining agent impregnated with the humidifying water and the accommodating chamber of the deodorant disposed separately from this accommodating chamber through the breathable member are integrally formed. The water impregnating the water retention agent in the storage chamber is configured to be diffused through the deodorant-filled layer in the storage chamber. Here, the "water retention agent" means a water absorbent resin, a super absorbent resin, a super absorbent polymer agent, and the like. The "breathable member" is a member that supports the deodorant and allows the water impregnated in the water retention agent to evaporate and pass through. For example, a breathable porous film, net, non-woven fabric, wire mesh, porous plate, thin paper, etc. is there. "Deodorant" is limited here to an adsorbent that removes with an adsorption effect. It is excellent in removing a small amount of malodorous components and easy to handle.

[0008]

[Action]

 According to the moisturizing / deodorizing device of the present invention, when the dehumidifying / deodorizing device is placed in a refrigerator or the like, moisture evaporates from the water retaining agent, thereby providing a moisturizing action. Then, since the moisture is diffused through the deodorant-packed layer, the moisture does not give off an offensive odor. In addition, since the deodorant is integrated with the water retention agent, deodorizing treatment is also performed. Further, since the deodorant covers the outlet through which the moisture of the water retention agent evaporates through the breathable member, the water impregnated in the water retention agent is not contaminated by the odor in the refrigerator.

【Example】

 Hereinafter, the present invention will be described in detail based on embodiments. (1) Embodiment 1 FIG. 1 shows an embodiment of a moisturizing deodorizer according to the present invention. This is a corner installation type for refrigerators. Reference numeral 1 represents a triangular prism-shaped synthetic resin case body. On the inner wall of the case body 1, some gussets 11 are projected at a position of about 1/2 height, and the plate-shaped breathable member 2 is placed on the gussets 11. The breathable member 2 is made of a breathable porous film.

The case body 1 is divided into a lower accommodation chamber 1 a and an upper accommodation chamber 1 b by the breathable member 2. The accommodating chamber 1a has a form of a receiver capable of accumulating an aqueous solution where a water retention agent 3 (described later) is accommodated. This is to prevent the water impregnated in the water retention agent 3 from seeping out of the case body 1. Reference numeral 4 indicates a cap that closes the through hole provided on the side surface of the accommodation chamber 1a. It is for makeup water. The storage chamber 1b is a place for storing a deodorant 5 (described later), and a large number of slits 12, 12, ... Are formed around the storage chamber 1b. The slit 12 is used to deodorize and moisturize the inside of the refrigerator.

Reference numeral 3 indicates a water retention agent. Here, as the water retention agent 3, an acrylic non-woven fabric type (manufactured by Toyobo; Lanseal NP-6) superabsorbent polymer agent was used. The water retention agent 3 is not limited to this, and a water absorbent resin, a super absorbent resin, or the like can be used. Specifically, starch-acrylic acid graft polymerization resin, starch-polyacrylate resin, polyacrylate cross-linking product obtained by reverse phase polymerization in an organic solvent, polyacrylic acid and maleic anhydride copolymer Examples thereof include a water-absorbent resin obtained by cross-linking a reaction product of a polymer with a basic substance, and a cross-linked product of a copolymer of an olefin containing sulfonic acids and maleic anhydride. The water retention agent 3 is impregnated with water and stored in the storage chamber 1b.

Reference numeral 5 represents a deodorant composed of a silica sheet (trade name) manufactured by Cosmore Asphalt Co., Ltd. The silica sheet is made by processing silica black, a natural ore, into a special polyethylene sheet. Silica black, which is the main component of the silica sheet, is porous and has the function of adsorbing malodor. In particular, it has an excellent adsorption capacity for formaldehyde, ammonia, hydrogen sulfide, etc. generated by food spoilage. Not only that, it has excellent far-infrared radiation ability at room temperature. Far infrared rays are said to have the function of activating cells and preventing decay. It is thought that the energy of far infrared rays makes water molecules finer and activates cells. Therefore, the deodorant 5 made of a silica sheet has a freshness maintaining function in addition to the deodorizing function. By the way, the deodorant 5 is not limited to the silica sheet, and various adsorbents can be used. Specifically, it is activated carbon, activated clay, activated alumina, bone charcoal, silica gel, synthetic zeolite, synthetic resin adsorbent (for example, styrene and divinylbenzene copolymer). .

In the moisturizing deodorizer configured as described above, since the water retention agent 3 is stored in the storage chamber 1b, the water impregnated in the water retention agent 3 does not spill out from the moisture retention deodorizer. Further, the impregnated moisture evaporates when the inside of the refrigerator dries, but this moisture cannot diffuse unless it passes through the breathable member 2 and passes through the packed layer of the deodorant 5. Therefore, odor does not drift in the refrigerator due to such humidifying operation. In addition, the superabsorbent polymer agent also has a unique odor, but there is no risk that it will spread to the inside of the warehouse due to the adsorption of the deodorant agent. On the contrary, if the odor in the refrigerator tries to get into the water of the water retention agent 3, the deodorant 5 that guards on the upper side of the water retention agent 3 will be adsorbed and removed, so that the water accumulated in the water retention agent 3 will be odorous in the refrigerator. It is not polluted with. In this way, it is possible to always release clean water to the inside of the refrigerator to secure a desired moisturizing state. Further, the deodorizing agent 5 removes a bad odor by its own adsorption action, and in addition, in the present embodiment, it emits far infrared rays, which is effective in maintaining freshness.

By the way, since such a moisturizing deodorizer uses an adsorbent, it will be restored if the adsorption equilibrium is disturbed by performing heating regeneration or the like, and if the water retention agent 3 also needs to be rehydrated, the cap 4 is removed. Since it can be replenished, it has the advantage of being able to be used permanently. Further, such a moisturizing deodorizer is small and convenient because the water retaining agent 3 and the deodorizing agent 5 are integrated and is inexpensive, which is useful for household refrigerators.

As a result of the test use of the moisturizing deodorizer, it has become possible to prolong the freshness of fresh foods and the like by preventing the cells from being dried by far-infrared ray activating effect and moisturizing effect. Moreover, even if the food materials that generate various odors are mixed and stored, the odor is less likely to be felt when opening and closing, and it is possible to prevent each food material from having other odors.

(2) Embodiment 2 This embodiment is a quadratic prism shaped moisturizing deodorizer as shown in FIG. The case body 1 is used in a horizontal position, and the top of the pedestal 13 is a storage chamber 1a for the water retention agent 3 and is partitioned by the breathable member 2, and the upper portion thereof is a storage chamber 1b for the deodorant 5. The storage chamber 1b has a structure like a receiver so that the water of the water retention agent 3 does not spill out. Reference numeral 12 indicates a slit provided in the storage chamber 1b. Like the first embodiment, deodorization and moisturizing are performed through the slits 12.

By the way, in this example, a graft starch superabsorbent polymer agent (manufactured by Sanyo Kasei; Sunwet IM-1000) was used as the water retention agent 3. Further, coconut shell granular activated carbon was used as the deodorant 5. The deodorant 5 is placed in a breathable non-woven bag so as not to go out of the case body 1. Reference numeral 4 indicates a cap that closes the through hole for supplying water.

Although the moisturizing / deodorizing device thus configured does not have the function of maintaining freshness by far infrared rays as in Example 1, it was possible to obtain excellent deodorizing and moisturizing effects. As in Example 1, it was economical because it was simple, not mechanical, and simply placed in the refrigerator.

It should be noted that the present invention is not limited to the one shown in the above-mentioned embodiment, and various modifications can be made within the scope of the present invention depending on the purpose and application. For example, the shape of the case body 1, the arrangement configuration of the storage chamber 1a and the storage chamber 1b, and the like can be appropriately selected. The storage chamber 1a and the storage chamber 1b may be arranged in multiple layers. The storage chamber 1a and the storage chamber 1b may be initially separate and later combined. Further, the deodorant 5 and the water retention agent 3 that enter the storage chamber 1a and the storage chamber 1b are not limited to one kind of filling, and may be mixed and combined.
