Description

  The present invention relates to a water-lifting sheet for a natural vaporizing humidifier that humidifies by natural evaporation of water and a natural vaporizing humidifier using the same.

  2. Description of the Related Art Conventionally, a natural vaporization type humidifier is known that utilizes the capillary phenomenon of paper, non-woven fabric, etc., and naturally vaporizes water in a humidifying container to prevent drying indoors or cars (for example, Patent Document 1) ). The humidifier of Patent Literature 1 forms a plurality of humidifying pieces by bending a water-lifting sheet into a predetermined shape. Specifically, as shown in FIG. 1 and FIG. 2 of Patent Document 1, the water-lifting sheet is folded in two around the center folded portion, and the center is formed in the middle portion excluding both ends of the center folded portion. A plurality of humidifying pieces are formed by forming a slit and folding the slit around a plurality of section bent portions parallel to the central bent portion in a direction perpendicular to the central bent portion. The obtained humidifier is used standing in a container such as a cup or tray containing water.

However, the water-lifting sheet of the humidifier of Patent Document 1 is formed from a sheet that does not have a vent hole. Therefore, the wind which collided with the water-lifting sheet from the front will decrease the flow velocity due to the collision. In particular, the wind impinging on the center of the sheet is significantly reduced, and the amount of water sucked up by the water-lifting sheet by capillary action is greatly reduced in the center of the sheet compared to the outer periphery of the sheet.
In addition, when a plurality of identically shaped water-lifting sheets are arranged in parallel with the humidifying container with the surface facing the wind, the wind hits only the windward water-feeding sheet and the second and subsequent sheets. Almost no wind hits the water-lifting sheet, and the amount of water evaporated by the wind cannot be increased.
Furthermore, the humidifier of Patent Document 1 uses a water-lifting sheet having a plurality of humidifying pieces formed by bending into a predetermined shape as described above, with the lower portion inserted into a cup or tray containing water. Yes. Therefore, the operation | work which bends a water-lifting sheet | seat and forms in a some humidification piece is troublesome. Moreover, even if the humidifier is shaped into a desired shape, it is easily deformed by a slight impact such as touching during use.

Water pumping material, water pumping sheet for natural vaporizing humidifier (water pumping material)
Here, the water-lifting material indicates a material capable of continuously pumping water by capillary action, and the material is not particularly limited as long as water can be pumped continuously by capillary action. As the water-lifting material, for example, a synthetic fiber cloth, porous ceramics, a rigid body such as wood, and a porous body such as a soft foamable synthetic resin can be employed.

<Water-lifting sheet for natural vaporizing humidifier>
Moreover, a water-lifting sheet | seat shows the planar sheet | seat which can pump water continuously by a capillary phenomenon. The term “planar sheet” as used herein refers to a flat sheet (plate) that is not bent.
As a material for the water-lifting sheet, for example, paper, fabric (woven fabric, nonwoven fabric, knitted fabric), sponge sheet, or the like can be used. Specifically, dry nonwoven fabrics made of synthetic fibers such as polyester fibers, polyamide fibers, polyolefin fibers, vinyl chloride fibers, core-sheath type or side-by-side type thermal adhesive composite fibers, rayon fibers, etc. A thick sheet or the like subjected to calendering, embossing, pressing or resin processing can be suitably employed. It is desirable to mix the antibacterial fungicide with the nonwoven fabric fiber so that germs and molds are not generated even when water is adsorbed on the water-lifting sheet. The fiber structure of the sheet is not limited to non-woven fabric, and may be, for example, a sheet of water-lifting obtained by applying resin processing to a woven fabric. In any case, water can be pumped continuously by capillary action. There is no limitation as long as there is. The color of the water-lifting sheet is arbitrary. For example, green, gray, pink, etc. are mentioned.

  As the water-lifting sheet, it is possible to employ a sheet used for a naturally vaporizing humidifier provided with a humidifying part at the upper part and a submerged part at the lower part. You may form a pair of latching convex part latched by the upper edge of the container in the both-sides edge part of a humidification part. By hooking the latching protrusion on the upper edge of the container, the stability of the water-lifting sheet set up on the container is enhanced. The forming range of the latching convex portion may extend over the entire length in the length direction of both side end portions of the humidifying portion or only the lower end portion thereof. Further, it is desirable that the lower end corner of each latching projection is an obtuse angle. This is because even if the humidifying part absorbs water and swells after long-term use, the tip of the lower end corner is less likely to be damaged than when the lower end corner is set to a right angle or acute angle. Increased maintenance of Although the protrusion width of the latching convex part is arbitrary, when it is the same as the width of the upper edge of the container, when the water-lifting sheet is set up on the container, this latching convex part collides with an obstacle etc. Since it is hard to break and the container and the water-lifting sheet are continuous without steps, the design of the natural vaporizing humidifier as a whole can be improved. Of course, the latching convex part does not need to be formed in the humidification part.

  The water-lifting sheet may be set up in a retaining groove formed on the inner surface of the container, or a sword mountain-shaped water-lifting sheet fixing tool may be provided in the container, and the water-lifting sheet may be set up detachably. The water-lifting sheet fixing tool here can easily fix (hang) or release (remove) a water-lifting sheet that humidifies air in a room or in a vehicle via the uneven hooking part. Refers to a member. The water-lifting sheet fixture may be formed integrally with the bottom plate of the container, or may be a separate body from the container and placed on the bottom plate. As the water-lifting sheet, a rectangular plate (rectangular card) or the like can be adopted.

<Vent hole>
A vent hole is formed through the front and back surfaces in the central portion of the humidifying portion. One or two or more ventilation holes may be formed. In the case of two or more, each vent hole is spaced apart by a predetermined interval. It suffices that at least one vent hole is formed at substantially the center of the humidifying part, and some vent holes may exist on the outer peripheral part of the humidifying part. As the shape of the vent hole, for example, a circular shape or a drop shape can be adopted. In addition, an arbitrary shape such as a quadrangle, an ellipse, a triangular polygon, or a star may be used.

Container The “container” used here is for storing water in which a water-lifting sheet is provided. As the material of the container, for example, various metals, various synthetic resins, various woods, various ceramics and the like can be employed. In addition, the shape of the container as viewed from above is arbitrary, for example, a circle, an ellipse, a triangle, or a polygon more than a quadrangle. Among these, when the water-lifting sheet is a rectangular plate, a rectangular container in a plan view is preferable for setting up through the retaining groove. When a natural vaporizing humidifier is used, water is stored in a container, and a water-impregnated portion of a water-lifting sheet set up through a retaining groove comes into contact with water.
The number of the water-lifting sheets to be set up in the container may be one or two or more. When a plurality of water-lifting sheets are set up in a container, the water-lifting sheets are spaced apart from each other. In addition, it is preferable that the ventilation holes formed in each water-lifting sheet are formed such that at least one of the numbers and shapes is different from each other. In this way, when the wind blows from one side of the length direction of the container, the wind does not pass straight through the insertion holes of all the water-lifting sheets existing from the upstream (upstream) to the leeward. While a part collides with the surface of each water-lifting sheet, it sequentially passes through each vent hole. As a result, the natural evaporation of the sucked-up water can be further increased in each water-lifting sheet.

<Hook groove>
As the latching groove, for example, a groove extending in the height direction of the rectangular container and formed on the inner surfaces of both side plates on the long side of the container at a predetermined pitch in the length direction of the container can be employed. . In addition, grooves that extend in the width direction of the container and are formed on the inner surface of the bottom plate of the container at a predetermined pitch in the length direction of the container can be employed. The latching groove may be formed only on the inner surfaces of both side plates on the long side of the container, or only on the inner surface of the bottom plate of the container, or on both of them. The groove width of the latching groove is, for example, substantially the same as the thickness of the submerged portion, and is preferably a width that can sufficiently latch the water-lifting sheet.
You may form the insertion guide groove part of the water-lifting sheet | seat which becomes wide gradually toward upper direction at the upper end part of each latching groove. At this time, the size of the insertion guide groove and the angle of the insertion guide groove that gradually expands upward are arbitrary.
Here, what includes at least a water-lifting sheet and a water storage container is referred to as a “natural vaporizing humidifier”.

Example 1
Hereinafter, a water-evaporating sheet for a naturally vaporizing humidifier according to Example 1 of the present invention will be described.
1 to 3, reference numeral 10 denotes a water vaporizing sheet for a natural vaporizing humidifier (hereinafter referred to as a water pumping sheet) according to Example 1 of the present invention, and constitutes a natural vaporizing humidifier A together with a container 11. The water pumping sheet 10 is made of a water pumping material, and is provided with a humidifying part 12 for naturally evaporating the sucked water from the surface at the upper part and a water immersion part 13 at the lower part. When used as the natural vaporizing humidifier A, the water-lifting sheet 10 is hooked up in the container 11 in a standing (vertical) state via a hooking groove 14 formed on the inner surface of the container 11.

Hereinafter, these components will be described in detail.
As shown in FIG. 1 and FIGS. 4 to 10, the water-lifting sheet 10 is made of a synthetic fiber nonwoven fabric (water-lifting material) whose front and back surfaces are pressed, and has a thickness of 0. A plurality of 7 mm sheets (here, 7 sheets). One large drop-shaped vent hole 15A is formed in the central portion of the humidifying portion 12 of the first water-lifting sheet 10A (FIG. 4). The center of the humidifying portion 12 of the second water-lifting sheet 10B Two middle-sized drop-shaped ventilation holes 15B are vertically formed in the section (FIG. 5), and a small drop-shaped ventilation hole 15C is formed at the center of the humidifying section 12 of the third water-lifting sheet 10C. Are formed vertically at a constant pitch (FIG. 6), and four small circular vent holes 15D are spaced apart at equal intervals vertically and horizontally at the center of the humidifying portion 12 of the fourth water-lifting sheet 10D. (FIG. 7) Five large circular vent holes 15E are formed in the shape of 5 dice in the center of the humidifying part 12 of the fifth water-lifting sheet 10E (FIG. 8). In the center of the humidifying part 12 of the sixth water-lifting sheet 10F, a large circular vent hole 15F is provided vertically. Three of them are formed at regular intervals (FIG. 9). At the center of the humidifying part 12 of the seventh water-lifting sheet 10G, there are four small circular vent holes 15G and four outer circles 8 Two (total of 12) are formed at regular intervals (FIG. 10). Among these, the water-lifting sheets 10A, 10D, and 10F are green, and the remaining four sheets are gray.

  A pair of hooks, which gradually taper toward the upper side over the entire length in the length direction (height direction) and whose lower end is hooked on the upper edge of the container 11, at both end portions of each humidifying section 12. The stop convex part 16 is formed of the same material. The stability of the water-lifting sheets 10 </ b> A to 10 </ b> G set up on the container 11 is increased by hooking both the latching protrusions 16 on the upper edge of the container 11. Moreover, the lower end corner | angular part of each latching convex part 16 is an obtuse angle of 120 degrees (FIG. 4 and FIG. 5). By comprising in this way, even if the humidification part 12 absorbs water and swells by long-term use, compared with the case where the lower end corner part 16a is made into a right angle or an acute angle, the tip part of the lower end corner part 16a It becomes difficult to break (defects, etc.), and the retention of this part increases. Further, the protruding width of each latching convex portion 16 is substantially the same as the width of the upper edge of the container 11. Thereby, when each water-lifting sheet | seat 10A-10G is set up in the container 11, these latching convex parts 16 collide with an obstruction etc., and it becomes difficult to be damaged, and the container 11 and each water-lifting sheet | seat 10A-10G Therefore, the design of the natural vaporizing humidifier A as a whole is enhanced. Further, the width of the submerged portion 13 is substantially the same as the width of the internal space of the container 11.

As shown in FIGS. 2 and 3, the container 11 is a deep plastic container having a rectangular shape that is horizontally long in plan view. The container 11 together with the water-lifting sheet 10 constitutes a natural vaporizing humidifier A.
The upper edges of the side plates 17 on the long side of the container 11 are notched in steps, except for both ends. In addition, thick base portions 19 are integrally formed at the four corners of the bottom plate 18 of the container 11.
On the inner surfaces of both side plates 17 on the long side of the container 11, the seven retaining grooves 14 extend in the height direction of the container 11 and at a predetermined pitch in the length direction of the container 11. Is formed. The groove width of each retaining groove 14 is substantially the same as the thickness of the flooded portion 13 of each of the water lifting sheets 10A to 10G, and is a width that can sufficiently latch the water lifting sheets 10A to 10G. In addition, insertion guide groove portions 14a for the water-lifting sheets 10A to 10G that are gradually widened upward are formed at the upper end portions of the respective retaining grooves 14. Thereby, when each water-lifting sheet | seat 10A-10G is set up in the container 11, it is easy to insert the water immersion part 13 in the corresponding latching groove | channel 14. FIG.

Next, with reference to FIGS. 1-10, the method at the time of using it as the natural vaporization type humidifier A is demonstrated about the water-lifting sheet | seat 10 of Example 1 of this invention.
As shown in FIG. 1, first to seventh water-lifting sheets 10 </ b> A to 10 </ b> G are set in a container 11 storing water in order from the right side in FIG. However, the arrangement order of the water-lifting sheets 10A to 10G is arbitrary. At this time, each water-lifting sheet | seat 10A-10G will be in the column state which made the opposite front and back parallel.
In this state, if wind blows from right to left, the wind is blown from the front against the surface of the first water-lifting sheet 10A. In the conventional product, there is no vent hole in the central part of the humidifying part, so the speed of the wind that collides with this central part is significantly reduced, and the natural evaporation of water from the central part of the humidifying part is the outer peripheral part of the humidifying part. However, in Example 1, since a predetermined number of air holes 15A to 16G are formed in the central portion of each humidifying portion 12, a part of the wind toward each humidifying portion 12 is part of these. A negative pressure region is generated in the entire back surface of the peripheral edge of each of the air holes 15A to 16G through the air holes 15A to 16G. Accordingly, air vortex streets are generated in these negative pressure regions, and as a result, the natural evaporation amount of water from the vicinity of the formation portions of the vent holes 15A to 16G of the humidifying portions 12 increases.
Further, when the wind toward the humidifying section 12 flows from the front side to the back side of the container 11 or from the back side to the front side, it passes between the water lifting sheets 10, so that the water from each water lifting sheet is The amount of natural evaporation increases.

Moreover, when each water-lifting sheet | seat 10A-10G is set up in the container 11, each water-lifting sheet | seat 10A-10G is mutually spaced apart. Moreover, the vent holes 15A to 16G formed in the water-lifting sheets 10A to 10G are different from each other in at least one of the number and the shape. In this way, when the wind blows from one side in the length direction of the container 11, the wind linearly passes through the vent holes 15A to 16G of all the water-lifting sheets 10A to 10G existing from the windward (upstream) to the leeward. Without passing through, a part of the water-impregnated sheets 10A to 10G collides with the surfaces of the water-lifting sheets 10A to 10G and sequentially passes through the vent holes 15A to 16G. As a result, in each of the water-lifting sheets 10A to 10G, the natural evaporation amount of the sucked water can be further increased. In the windless state, water naturally evaporates from the front and back surfaces of the humidifying unit 12 as in the case of the conventional water-lifting sheet.
Further, each of the water lifting sheets 10A to 10G is hooked in the hooking groove 14 of the container 11 in a standing state without being bent, and thus is lifted like a conventional product. The operation | work which bends a sheet | seat and forms in a some humidification piece becomes unnecessary.
