In the invention described in Patent Document 1, the idea of using a water-absorbing sheet as a sheet-shaped preserving material is disclosed. In this case, when the sheet is used, the contents that have absorbed moisture are concentrated downward due to the weight. In this case, when used as a simple moisturizing means, it cannot be used flexibly according to various usage modes.
Moreover, in the invention described in Patent Document 2, when the freshness maintaining material is arranged in the refrigerator, the structure of the refrigerator has to be partially changed and cannot be easily used with a simple structure.

  Therefore, the present invention provides a simple moisturizing filter using a water-absorbing sheet having a moisturizing effect, which is more suitable for moisturizing vegetables than conventionally known absorbent sheets, can be used easily, and the refrigerator itself The present invention provides a simple moisturizing filter and an arrangement member thereof that can increase the moisturizing effect in the refrigerator without changing the structure.

In the present invention, one or both of them has a water-absorbing resin between a top sheet and a back sheet that are breathable, and bonds the end portions of the top sheet and the back sheet. It uses a water absorbent sheet that has been quilted to be sewn,
The end of the water-absorbent sheet has an edge part to which only the top sheet and the back sheet are bonded, and the next water-absorbent sheet is sequentially formed from the end edge part to form a continuous sheet. A break line is formed at the edge between the adhesive sheets, and the unit sheet is a sheet cut for each break line,
A simple moisturizing filter characterized in that the unit sheet is separated into one unit or a plurality of units, and the surface corresponding to the length of the separated water absorbent sheet is housed in a water absorbent sheet housing filter pocket having air permeability.

  Moreover, it is preferable that the water-absorbent sheet has water absorbed in advance in the water-absorbent resin.

In addition, the front wall and the rear wall are connected by the bottom, upright in a state where a space portion is formed inside the front wall and the rear wall, and provided with openings in the front wall and the rear wall,
Quilting by placing a water-absorbing resin between the top sheet and the back sheet, one or both of which are air permeable, bonding the ends of the top sheet and the back sheet, and sewing the top sheet, the back sheet, and the water-absorbing resin Using a water-absorbent sheet that has been processed, the end of the water-absorbent sheet has an edge part to which only the top sheet and the back sheet are adhered, and the next water-absorbent sheet is successively formed from the edge part. It is in the form of a sheet, a break line is formed at the edge between successive water-absorbent sheets, and a sheet separated for each break line is a unit sheet,
A simple moisturizing filter is arranged, which is separated into one unit unit or a plurality of unit sheets, and the surface corresponding to the length of the separated water absorbent sheet is stored in a breathable water absorbent sheet storage filter pocket. Thus, there is a simple moisturizing filter arrangement member characterized in that the simple moisturizing filter is made to stand upright.

  In addition, as a method of using the simple moisturizing filter arrangement member, the front wall and the rear wall are connected by the bottom, and a space portion is formed inside the front wall and the rear wall, and the front wall and the rear wall are respectively upright. An opening is provided, and one or both of the openings are air-permeable, and a water-absorbing resin is disposed between the front sheet and the back sheet to bond the end portions of the top sheet and the back sheet. A water-absorbent sheet subjected to quilting processing for sewing water-absorbent resin, and forming an end portion in which only the top sheet and the back sheet are bonded to the end portion of the water-absorbent sheet, and from the end portion to the next Water-absorbing sheets are formed in order, formed into a continuous sheet, and a water-absorbing sheet is formed by placing a water-absorbing sheet characterized in that a break line is formed at the edge between successive water-absorbing sheets, and the water-absorbing sheet is disposed in a space portion. Upright sheet A method for using a water absorbent sheet arranging member that keeps a ventilation path and keeps moisture while arranging a water absorbent sheet arranging member along a wall surface of a vegetable indoor part of a refrigerator or as a partition of a vegetable indoor part There is.

According to invention of Claim 1, since it is a water absorptive sheet using a water absorptive resin, a water | moisture content can fully be absorbed. Since this water-absorbent sheet moisturizes the moisturized material, mainly vegetables, the moisture retaining effect can be increased by covering the moisturized material.
In addition, by applying quilting, it is possible to prevent the resin in the water absorbent sheet from moving to the lower part in the sheet, and to efficiently moisturize the entire moisturized material covered by the water absorbent sheet.
Moreover, since the temperature in the refrigerator can be lowered without increasing the cool air of the refrigerator, electric energy can be saved.
In addition, by disposing the water-absorbing sheet around the vegetables, the water-absorbing sheet absorbs dirt and the like of the vegetables, and also has an effect of removing dirt in the vegetable room and keeping clean.

In the first aspect of the invention, the water-absorbent sheet can be stored by a simple method by using a continuous sheet. In use, the water-absorbent sheets can be easily cut out one by one along the breaking line. Moreover, since only the top sheet and the back sheet are bonded to the edge portion, it is possible to use the separated water absorbent sheet without leakage of water from the water absorbent sheet. Thereby, a user can store a water-absorbent sheet easily, and can remove and use it.
Further, since the filter is put in the filter pocket, the water absorbent sheet is reinforced.

(Example)

Embodiments of the present invention will be described with reference to the drawings.
1 is a front view of the water absorbent sheet of the present invention, FIG. 2 is a cross-sectional view taken along the line AA of the water absorbent sheet of FIG. 1, FIG. 3 is a perspective view of a water absorbent sheet arrangement member, and FIG. FIG. 7 is a perspective view of a simple moisturizing filter.

As shown in FIG. 7, the simple moisturizing filter 101 of the present invention is formed by enclosing the water absorbent sheet 1 in a filter pocket 102.
As shown in FIG. 1, the water-absorbent sheet 1 has a water-absorbing resin 4 sandwiched between a top sheet 2 and a back sheet 3, one or both of which have air permeability, and the top sheet 2 and the back sheet 3 are adhered to each other. It is a single sheet. That is, the top sheet 2 and the back sheet 3 are either members having air permeability or one of them is a member having air permeability.
For the sheet having air permeability, a member having relatively high air permeability is used. Natural materials such as cotton and linen and paper members are preferred. When using a member having no air permeability, a film such as nylon is used.

The water absorbent sheet 1 is bonded by quilting with the water absorbent resin 4 sandwiched between the top sheet 2 and the back sheet 3. First, the quilting 5 for adhesion | attachment is made | formed along the outer edge part of the surface sheet 2 and a back surface sheet | seat outside the water absorbing resin. In this way, the water-absorbing resin 4 is sandwiched between the top sheet 2 and the back sheet 3 by sewing, so that the content of the resin does not fall from the top sheet and the back sheet 3.
Moreover, although not shown in figure, the sheet | seat of 1 sheet may be folded in the center, it may be set as the surface sheet 2 and the back surface sheet 3, and the water absorbing resin 4 may be pinched | interposed and bonded inside.

Moreover, the water-absorbent resin 4 used in the present invention is one in which a large number of small granular contents 7 are accommodated in a bag-shaped package. And the water-absorbent sheet 1 is maintained in a vertical state during use, or is maintained in an oblique direction. In this case, the granular contents 7 inside the water-absorbent resin 4 often concentrate downward due to gravity. In particular, when moisture is absorbed, the granular contents 7 are concentrated downward due to the weight of moisture. In order to enclose the water-absorbent resin 4 in the water-absorbent sheet 1 on average, in the present invention, the holding quilting 6 is performed from the top sheet 2 through the water-absorbent resin 4 to the back sheet 3. The holding quilting 6 has an effect of adhering the top sheet 2 and the back sheet because they are stitched together.
In some cases, the water-absorbent sheet may stand upright at the time of use, and the water-absorbent resin causes the granular content 7 to be averaged by the holding quilting 6 in order to effectively exert the moisture retaining effect of the water-absorbent resin as an entire sheet. Exist.

  The water absorbent resin 4 is made of a polymer absorbent such as polyacrylate. It is necessary that the water absorbent resin used in the water absorbent sheet 1 of the present invention can be maintained in a state containing moisture. The polymer absorbent is used in commercially available paper diapers and the like, and the polymer absorbent can be used by cutting out from such a paper diaper.

One or both of the top sheet 3 and the back sheet 4 is preferably one having good air permeability because the water absorbent resin 4 contains moisture and has a moisturizing effect. For this reason, it is not preferable to use a sheet having poor air permeability such as a vinyl chloride sheet.
As the air-permeable member, Japanese paper having water absorption and moisture retention may be used.

As shown in FIG. 8, the water-absorbent sheet 1 is formed in a state where a continuous sheet 8 is continuous from the end. Since the water-absorbent sheet 1 is made continuous, it can be stored while being wound around the roll core 9. The edge 11 of the water absorbent sheet 1 is formed with the edge 11 where the top sheet 2 and the back sheet 3 are bonded together with the water absorbent resin 4 not being sandwiched between them. A break line 10 is formed at the edge portion 11 between the continuous water absorbent sheets 1, and is cut along the break line 10 when used to be used as a single water absorbent sheet 1.
Although not shown, the continuous sheet 8 can be folded and stored without being rolled.

As shown in FIG. 7, the filter pocket 102 uses a net-like pocket having a relatively large mesh. The filter pocket 102 shown in the embodiment has a front surface 103 made of a mesh member and a back surface 104 made of a film. That is, it is formed so that one side has air permeability and the other side does not have air permeability.
The filter pocket 102 is obtained by adhering peripheral portions other than the upper edges of the front surface 103 and the rear surface 104. The upper edge forms an opening 105 to create a storage space between the front surface 103 and the back surface 104, and the water absorbent sheet 1 can be stored in the storage space. The water absorbent sheet 1 is accommodated in the filter pocket 102 to form the simple moisturizing filter 101 of the present invention.

  The water-absorbing sheet 1 can be cut and used with an appropriate length by the breaking line 10 of the continuous sheet 8, but the water-absorbing sheet for each breaking line can be used as a unit sheet, and also used as a two-unit sheet. The filter pocket 102 is used by connecting the filter pocket 102. By connecting the filter pockets in this way, it is easy to change the length of the water-absorbent sheet appropriately depending on the object used by the user and the size of the vegetable room in the refrigerator. Become.

Next, the arrangement | positioning member 31 for arrange | positioning the simple moisturizing filter 101 effectively in a refrigerator is demonstrated.
As shown in FIG. 3, the arrangement | positioning member 31 is a member which has a box-shaped form.
The arrangement member 31 is formed of a synthetic resin material.
The arrangement member 31 includes a front wall 32, a rear wall 33, side walls 34 and 34, and a bottom surface 35, and forms a space portion. A concave portion 36 is formed in the upper edge portion of the front wall 32 and the rear wall 33. A plurality of openings 37 are formed in lower portions of the front wall 32 and the rear wall 33.
The arrangement member 31 is provided with an opening 37 and a recess 36 in order to provide not only the simple moisture retention filter 101 in the space but also the moisture retention effect of the water absorbent sheet. The water contained in the water-absorbent sheet is diffused by the openings 37 and the concave portions 36, and the place arranged by the arrangement member can be moisturized.

  As shown in FIG. 4, the second example of the arrangement member is an arrangement member 31 including a right arrangement portion 41 and a left arrangement portion 42. Each of the right side arrangement part 41 and the left side arrangement part 42 has a form in which the arrangement member 31 according to the first embodiment is divided at the center in the lateral direction. That is, the right side arrangement portion 41 also includes the front wall 32, the rear wall 33, the side wall 34, and the bottom surface 35. A concave portion 36 is formed in the upper edge portion of the front wall 32 and the rear wall 33, and a plurality of openings 37 are formed in lower portions of the front wall 32 and the rear wall 33. The left side is the same for part 42.

  The right side arrangement part 41 and the left side arrangement part 42 can be used when the arrangement member 31 of the first embodiment prepared in advance does not match the length of the simple moisturizing filter 101. That is, when the horizontal direction of the simple moisturizing filter 101 is longer than the arrangement member 31 of the first embodiment, the right arrangement part 41 and the left arrangement part 42 support both ends of the simple moisturization filter 101 in the lateral direction. Can be arranged. Therefore, when using the right side arrangement | positioning part 41 and the left side arrangement | positioning part 42 concerning 2nd Example, it can arrange even when the length of the horizontal direction of the simple moisturizing filter 101 becomes long. That is, it is possible to flexibly cope with a change in the size of the simple moisturizing filter 101 to be used.

Next, the usage method of the simple moisturizing filter 101 will be described.
Moisturizing effect can be improved by a simple method by adding moisture to the water-absorbing sheet 1 of the simple moisturizing filter 101 and coating the moisture retention target substance. In particular, when fresh food such as vegetables 53 is moisturized, it can be moisturized by a simple method, and the preservation effect can be improved.

In order to make the water absorbent sheet 1 contain moisture, although not shown in the drawing, the water absorbent sheet 1 is made to contain water from the outside of the top sheet and the back sheet by ejecting moisture with a sprayer. When the water-absorbent resin 4 having a thickness of 0.1 to 0.2 mm is used as the target, the water is preferably 300 cc to 400 cc per 400 square centimeters of the water-absorbent sheet 1. That is, the moisture is preferably 75 to 100 cc per 100 square centimeters. When the amount of water is less or greater than this, it becomes difficult to achieve a moisturizing effect suitable for vegetables.
This is a case where the coating material is vegetable, and when it is used in the vegetable compartment 52 of the refrigerator, about 60% of the coating is appropriate to circulate the cold air. As a result of the experiment, the above water content was most appropriate.
When the moisture absorbed by the absorbent resin 4 disappears due to the use of the water absorbent sheet 1, the water is ejected from the surface of the water absorbent sheet 1 by a sprayer so that the moisture is contained, and it can be used repeatedly. is there.

  Next, a method for using the simple moisturizing filter 101 using the arrangement member 31 will be described. As shown in FIGS. 5 and 6, the arrangement member is mainly placed inside the vegetable compartment 52 of the refrigerator 51 and arranged with the simple moisturizing filter 101 supported.

FIG. 6 is an enlarged view of only the vegetable compartment 52 of FIG.
Arrangement should just cover the inside of vegetable room 52. As described above, in order to have an appropriate moisturizing effect, it is preferable to cover approximately 60% of the inner surface of the vegetable room. Cold air is blown in the refrigerator, and if the cold air is cut off, the temperature in the vegetable compartment rises, and conversely, the vegetable storage period is shortened. In the embodiment shown in FIG. 6, a simple moisturizing filter 101 is laid on the bottom of the vegetable room, one arranging member 31 is placed on the right side, left side, and center, and three simple moisturizing filters 101 are placed on the front. 31 is arranged.
Placing a simple moisturizing filter on the bottom surface not only increases the moisturizing effect in the refrigerator, but also has an effect of preventing soiling of the bottom of the vegetable compartment due to dripping of vegetable moisture.
FIG. 10 shows another embodiment in which the simple moisturizing filter 101 is also covered on the upper side of vegetables from the arrangement state of the simple moisturizing filter 101 in FIG.

The arrangement of the vegetable room needs to circulate cold air as a function of the refrigerator 51, and as long as it covers about 60% of the vegetable room surface as described above. The size and shape of the vegetable room varies depending on the refrigerator model, and it is necessary to change the arrangement method depending on the size and shape of the refrigerator.
Further, the vegetable compartment can be divided into 2 to 4 compartments by using the arrangement member 31 containing the simple moisturizing filter 101 as a partition. Thereby, moisture retention can be raised efficiently and the preservation | save period of the vegetables 53 can be lengthened. In the embodiment shown in FIG. 6 as well, the arrangement member 31 arranged near the center functions as a partition, and the vegetable compartment is divided into two compartments.

  As shown in FIG. 9, the simple moisturizing filter 101 can be arranged in a booklet 61 that can be attached in the vegetable compartment 51. The booklet 61 is detachably installed on the inner side surface of the vegetable room. The booklet can be provided with one or more simple moisturizing filters 101. If the simple moisturizing filter continues to be used and needs to be replaced due to deterioration or the like, it can be removed from the booklet 61 and a new simple moisturizing filter can be placed.

The humidity in the refrigerator is normally kept at about 45%, but if the simple moisturizing filter 101 is arranged with a coverage of about 60%, the humidity can be increased to 70-80%. This is because the moisture absorbed by the simple moisturizing filter 101 is supplied to the vegetable compartment as a humid gas.
In addition, when using the simple moisturizing filter 101 in the vegetable compartment, it is possible to increase the humidity by increasing the cold air strength setting in the vegetable compartment to about 5 degrees. The reason is that the circulating cold air becomes stronger and more humid gas is supplied into the vegetable compartment.
By setting it as such a humid state, it can prolong the wilt of vegetables than usual, and the preservation | save of vegetables 53 can be extended.

  Although not shown, the simple moisturizing filter 101 can also be used in a simple storage box made of a polystyrene foam material that is used relatively frequently for transporting fresh fish. By using it in a simple storage box, the contents such as fresh fish can be moisturized and the freshness can be maintained for a long time.
