Description

  The present invention relates to a natural evaporation humidifier that humidifies air by natural evaporation of water, a humidifying element thereof, and a case for the humidifier.

  Conventionally, a natural evaporation humidifier that does not use electric power has been used to prevent drying of indoor air by a heating device or the like. As shown in FIG. 7, a conventionally known humidifier 70 includes a humidifying material 72, a water tank 74, a container 76, a cover 78, and the like. The humidifying material 72 is made of a synthetic resin or the like that absorbs water, and a capillary phenomenon is utilized by immersing a part of the humidifying material 72 (a suction part 72a) in water contained in a container 76. Then, the water is sucked up and the entire humidified material 72 is included. The water absorbed by the humidifying material 72 naturally evaporates from the surface (humidifying portion 72b) of the humidifying material 72 by contacting with the indoor air passing through the slit 80 provided in the cover 78, thereby bringing moisture into the room.

  However, the humidifier 70 having the above configuration is a large-scale configuration and cannot be carried. In order to carry it, the humidifier must be reduced in size and weight, but in order to secure a desired amount of humidification, the number of humidified materials must be increased or the size of the humidified material must be increased. Thus, since miniaturization and weight reduction of a humidifier are contrary to the humidification capability, it is extremely difficult to reduce the size and weight, so it is impossible to carry the humidifier. In addition, the larger the humidifying material, the more difficult it is to wet away from the dipping position, and there is a problem that it takes time until the entire humidifying material is wetted, making it difficult to quickly humidify. In addition, the humidifier 70 configured as described above is expensive in cost and cannot be easily purchased and installed.

  The inventor of the present application has developed a portable natural evaporative humidifier that achieves a reduction in size and weight. A natural evaporative humidifier reduced in size and weight is shown in FIGS. The natural evaporation humidifier 100 shown in FIG. 8 includes a case 106 including a container 102 for storing a liquid and a lid 104 of the container 102, and a humidifying element 108 accommodated in the case 106.

  The humidifying element 108 is assembled in a three-dimensional shape shown in FIG. 10 by bending the flat state shown in FIG. 9 several times, and the humidifying element 108 assembled as shown in FIG. Install and use inside. From the state of the humidifying element 108 in the planar state shown in FIG. 9, it is bent in two at the central bent portion 110 along the center in the longitudinal direction, and further parallel to the central bent portion 110 at substantially equal intervals in a substantially perpendicular direction. Are bent in such a manner that the bending direction is changed in order along the section bending portion 112. Each of the partition bent portions 112 is provided with a slit 113 for passing the air and promoting the evaporation of water. A plurality of humidifying pieces 114 (FIG. 9) are formed by bending the humidifying element 108 at the center bent portion 110 and the plurality of compartment bent portions 112. The plurality of humidifying pieces 114 are divided into two portions divided by the central bent portion 110 on one end side, an end humidifying piece 114aa and an end humidifying piece 114ab, and two end humidifying pieces 114ba and an end on the other end side. It consists of a humidifying piece 114bb and a plurality of intermediate humidifying pieces 114c formed between them.

  The horizontal widths of the plurality of intermediate humidifying pieces 114c are the same, and the horizontal widths of the end humidifying pieces 114aa and the end humidifying pieces 114ab on one end side are set wider than the horizontal width of the intermediate humidifying pieces 114c. The end humidifying piece 114aa is formed with a fitting hole 116 for fitting to a pin to be described later, and an engagement slit 118 for engaging an insertion piece to be described later. An engagement hole 120 is formed in the intermediate humidification piece 114c adjacent to the end humidification piece 114ba, and engagement holes 122a and 122b are formed in the plurality of intermediate humidification pieces 114c close to the end humidification piece 114bb. A connecting piece 124 connected to the central bent portion 110 is provided adjacent to the end humidifying piece 114ba. For example, a semicircular cut line 126 is formed at the center of the connecting piece 124, and an insertion piece 128 is formed by the cut line 126. This insertion piece 128 is engaged with the engagement slit 118 formed in the end humidifying piece 114aa.

  In order to assemble the planar humidifying element 108 shown in FIG. 9 into the three-dimensional state shown in FIG. 10, first, it is folded along the central folding part 110, and the two folded areas are overlapped, and then a plurality of These are bent in order along the section bending portion 112 to form an expandable and contractible bellows shape. Next, the connecting piece 124 is bent toward the humidifying piece 114aa, and the insertion piece 128 of the connecting piece 124 is inserted into the engagement slit 118 of the humidifying piece 114aa. Thus, the humidifying element 108 is assembled into the three-dimensional shape shown in FIG.

  As shown in FIG. 8, a protrusion 130 as a hinge is formed on the container 102, and a lid 104 is swingably attached around the position of the protrusion 130. The container 102 is formed with an internal space 132 that is a water reservoir. As shown in FIG. 11, the container 102 is formed by fixing a base portion 134 and an overhang portion 136 that protrudes from the base portion 134 toward the internal space 132, and includes a lower end of the overhang portion 136 and an inner bottom surface of the base portion 134. A gap 137 is formed between them. A pin 138 protruding upward is formed on the bottom surface of the base portion 134. The pin 138 is fitted into a fitting hole 116 formed in the end humidifying piece 114aa.

  In order to attach one end of the humidifying element 108 to the container 102, as shown in FIG. 11, the outer edge of the end humidifying piece 114aa (the outer edge on the side opposite to the partition folding part 62) is connected to the lower end of one overhanging part 136 and the container. The hole 116 is inserted into the gap 137 between the bottom surface of 102 and the fitting hole 116 of the end humidifying piece 114aa is fitted to the pin 138 of the container 102. Further, the outer edge of the humidifying piece 114ab (the outer edge on the side opposite to the partition folding part 62) is inserted into the gap 137 between the lower end of the other overhanging part 136 and the bottom surface of the container 102. Thereafter, a holding plate 140 (FIGS. 11 and 12) made of a material that bends when force is applied but returns to its original flat shape when the force is removed is used. The holding plate 140 is end humidified piece 114aa or end humidified. The both ends of the holding plate 140 are disposed below the lower ends of the overhanging portions 136 on both sides, through the slits 113 of the section bending portion 112 at a position close to the piece 114ab. The holding plate 140 is brought into contact with the lower end side of the pair of overhang portions 136 by the upward return force of the end humidifying piece 114aa, the end humidifying piece 114ab, the intermediate humidifying piece 114c, and the like positioned below the holding plate 140, Thereby, the humidifying element 108 is fixed to the container 102.

  As shown in FIG. 8, the lid 104 is integrally formed with left and right engaging arms 142 (only one is shown). When the humidifying element 108 is attached to the lid 104, the engaging hole 120 formed in the humidifying element 108 is engaged with one engaging arm 142, and the engaging holes 122a and 122b formed in the humidifying element 108 (in FIG. 8). (Not shown) is engaged with the other engagement arm 142. As a result, the other end of the humidifying element 108 can be attached to the lid 104.

  When the humidifier 100 is used, the lid 104 is opened with respect to the container 102. As a result, both ends of the humidifying element 108 housed in the internal space 132 are pulled in opposite directions by the container 102 and the lid 104, and the humidifying element 108 is deformed and opened in a fan shape (FIG. 8). As a result, at the time of use shown in FIG. 11, the plurality of intermediate humidifying pieces 114c of the humidifying element 108 are arranged in two rows and alternately with the positions of the petals changed. That is, the humidifying pieces 114 of all the intermediate humidifying pieces 114c are separated from each other, and the evaporation of moisture from each humidifying piece 114 can be promoted.

  In a state where the humidifying element 108 is opened in a fan shape, the connecting piece 124 is in the position of the fan shape. However, the size and shape of the humidifying element 108 are always located below the internal space 132 of the container 102. Is set. As a result, when a liquid such as water is put in the internal space 132 of the container 102, one end of all the humidifying pieces 114 covered with the connecting piece 124 is immersed in water, and each humidification is performed by capillary action from the place immersed in water. Water can be moistened above the strip 114 in a short time. Moreover, since the humidification element 108 has many humidification pieces 114 opened in the shape of a fan, evaporation of a large amount of moisture can be promoted.

  In the natural evaporation humidifier 100, the humidifying element 108 is opened and closed in a bellows shape by opening and closing the lid 104. At this time, the fixing position of the humidifying element 108 with respect to the container 102 is the position of the fitting hole 116 that fits the pin 138 of the container 102. For this reason, when the lid 104 is opened and closed, the humidifying element 108 at a position close to the lid 104 rotates around the pin 138 and moves in the lateral direction of the container 102 (arrow AA direction in FIG. 12). For this reason, when the lid | cover 104 was opened, there existed a possibility that the humidification element 108 might not open in a fan shape in the stable state. Further, when the lid 104 is closed, the humidifying element 108 may not be folded smoothly.

  Further, when the lid 104 is opened, the force concentrates on the position of the fitting hole 116 that engages with the pin 138 in the humidifying element 108, and there is a possibility that tearing may expand from the fitting hole 116. Furthermore, there is a possibility that the tears may expand from the slits of the section bending portion 112 that passes through the holding plate 140.

  The container 102 is composed of two different types of parts, that is, a base part 134 and an overhang part 136 for pressing one end of the humidifying element 108, and the base part 134 and the overhang part 136 are welded to each other. The container 102 formed by welding two types of parts is expensive to manufacture. Further, the holding plate 140 for fixing the humidifying element 108 to the container 102 has to be prepared as a separate part, which not only increases the cost of the parts but also may cause the holding plate 140 to be lost. Further, since the overhang portion 136 is provided inside the container 102, it was difficult to discharge the water in the container.

  The present invention has been made in view of the above problems, and prevents the humidifying element from laterally shaking when the lid is opened and closed so that the humidifying element can be reliably opened and folded into a fan shape and when the lid is opened and closed. The present invention provides a natural evaporation humidifier, a humidifier element, and a case for the humidifier, in which a portion where force concentrates on the humidifier element is eliminated to prevent breakage.

In order to solve the above-mentioned problems, a natural evaporation humidifier according to the present invention houses a humidifying element having a water absorption property, which is formed by connecting a plurality of humidifying pieces together with a plurality of humidifying pieces, and the humidifying element. A container having an internal space; a lid attached to the container for opening and closing the container; first attaching means for attaching one of the humidifying elements and the container; and a first attaching means for attaching the other of the humidifying elements and the lid. Two attachment means and a pair of guide portions that are provided in the internal space of the container and guide the humidifying element in a direction sandwiched between both sides of the humidifying element when the lid is opened and closed. It is characterized by. In the present invention, the first attachment means includes an engagement arm formed on the container and a first engagement hole formed on the humidifying element and engaged with the engagement arm . The two attachment means comprises an engagement arm formed on the lid and a second engagement hole formed in the humidifying element for engaging with the engagement arm formed on the lid . In the present invention, a plurality of folds are formed by bending the humidifying element into a central fold portion that is bent in two along the longitudinal direction thereof and a plurality of compartment fold portions formed by bending the central fold portion in a substantially perpendicular direction. The humidifying piece is formed, and any one of the first engagement hole and the second engagement hole is a hole formed in parallel to the compartment bending portion of the plurality of humidifying pieces. To do. The present invention is characterized in that a wall of the container at a position facing a wall connecting the pair of guide portions in the container is inclined outward and directed upward. In the present invention, a protrusion is formed on the outer surface of the container or the lid, a fitting portion is formed on the outer surface of the lid or the container to be fitted with the protrusion, and the protrusion and the fitting portion are fitted. In the state, the projection and the fitting portion are not detached from each other unless an external force is applied to at least one of the container or the lid. In the present invention, the humidifying element includes a connecting piece formed on the humidifying element, an insertion piece formed by a cut line formed on the humidifying element at a location other than the connecting piece or the connecting piece, and a connecting piece other than the connecting piece. It is formed in the humidifying element or the connecting piece at a location, and has a connecting means including an engaging slit that engages with the insertion piece.

Humidifier element of the present invention forms a plurality of humidifying pieces sequentially coupled through the plurality of sections bent portion by bending a sheet-like member a plurality of parallel compartments bent portion having a water absorption, the An engagement hole substantially parallel to the partition folding portion is formed in at least one humidifying piece at the end of the plurality of humidifying pieces .

The humidifier case of the present invention includes a container having an internal space for accommodating a humidifying element composed of a plurality of humidifying pieces, and a lid that is swingably attached to the container and opens and closes the internal space. be one having a, with the pair of guide portions for guiding the humidifying element in the sandwiched direction with be those provided in the interior space interposed therebetween on both sides of the humidifying element during opening and closing of the lid of the container it is characterized in that the. The present invention is characterized in that the wall of the container at a position facing the wall connecting the pair of guide portions in the container is an inclined wall that is inclined outward toward the upper side. In the present invention, a protrusion is formed on the outer surface of the container or the lid, a fitting portion is formed on the outer surface of the lid or the container to be fitted with the protrusion, and the protrusion and the fitting portion are fitted. In the state, the projection and the fitting portion are not detached from each other unless an external force is applied to at least one of the container or the lid.

  The natural evaporation humidifier of the present invention is small, lightweight and portable by housing the humidifying element in a case composed of a container and a lid. The natural evaporation type humidifier of the present invention uses a humidifying element composed of a plurality of humidifying pieces, bundles one end of the plurality of humidifying pieces, and sandwiches both sides of the width of the plurality of humidifying pieces at the bundled portion with walls. By guiding, the humidifying element (a plurality of humidifying pieces) is prevented from moving laterally when the lid is opened and closed. When the lid is opened and closed, the humidifying element prevents the humidifying piece from moving in the width direction, so that the humidifying element can be reliably opened in a stable fan shape when the lid is opened, and the humidifying element is smoothly folded when the lid is closed. It becomes possible.

  In the present invention, an engagement hole that engages an engagement arm provided on a container or an engagement arm provided on a lid is formed in the humidifying element, and the engagement hole is formed in the opening / closing movement direction of the lid (partition folding of the humidifying element). Part). As a result, when the lid is opened and closed, the humidifying element moves in the direction of movement of the lid. At this time, the engagement arm does not come into contact with the end of the long engagement hole, so there is no place where the force is concentrated on the humidification element. Further, the humidifying element can be prevented from being damaged. Since there is no location where force is applied to the humidifying element, the lid can be opened and closed smoothly.

  Since the container of the present invention is composed of one member, the manufacturing cost can be reduced as compared with a conventional case in which two types of separate parts are welded. In addition, since the conventional holding plate for holding the humidifying element in the container is not required, the cost of parts can be reduced, and the worry of losing the holding plate can be eliminated. Furthermore, water can be easily poured into and drained from the internal space of the container by making one wall of the container inclined upward and facing upward.

  Next, the present invention will be described with reference to the drawings. 1 is a perspective view showing a state in which a natural evaporation humidifier according to the present invention is opened, FIG. 2 is a plan view of FIG. 1, FIG. 3 is a plan view of a humidifying element used in the present invention, and FIG. FIG. 4 is a perspective view showing a state in which the humidifying element of FIG. 3 is folded and assembled. The natural evaporation humidifier 10 according to the present invention includes a case 16 including a container 12 for storing a liquid and a lid 14 of the container 12, and a humidifying element 18 accommodated in the case 16.

The humidifying element 18 (FIG. 3) consists of a sheet-like thing which has water absorption, and is comprised by the sheet | seat of one sheet | seat whose one side is longer than the other side. The humidifying element 18 is preferably made of a synthetic resin such as polyester or rayon, but any material that can absorb and evaporate water may be used. Moreover, it is desirable to mix an antibacterial / antifungal agent with a material such as a synthetic resin so that germs and molds are not generated even when water is adsorbed.

  The humidifying element 18 is used by being folded several times from the planar state shown in FIG. 3 and assembled into the three-dimensional shape shown in FIG. The humidifying element 18 shown in FIG. 3 forms a central bent portion 20 for folding in half, that is, in two along the center in the longitudinal direction. The central bent portion 20 is not linear, The straight line is bent left and right several times. In this humidifying element 18, a plurality of divided bent portions 22 are formed in each of the two regions divided by the central bent portion 20 and parallel to the central bent portion 20 at substantially equal intervals in a substantially perpendicular direction. Bending is performed so as to change the folding direction in order along the plurality of section folding portions 22. A slit or notch 21 is formed in a part of the length of the central bent part 20 or a part of the length of each divided bent part 22. These slits and notches 21 are for facilitating the bending of the central bent portion 20 and the compartment bent portion 22 and for allowing air to pass through the positions of the slits and the notches 21.

  A plurality of humidifying pieces 24 are formed by bending the humidifying element 18 at the center bent portion 20 and the plurality of compartment bent portions 22. On one end side of the humidifying element 18, the two portions divided into two at the central bent portion 20 are defined as an end humidified piece 24aa and an end humidified piece 24ab, and two at the central bent portion 20 on the other end side. The two divided locations are referred to as an end humidifying piece 24ba and an end humidifying piece 24bb, and a plurality of locations between these ends are referred to as intermediate humidifying pieces 24c. If the width of the intermediate humidifying piece 24c is C, the width of the end humidifying piece 24aa and the end humidifying piece 24ab is larger than the width C of most portions, and the notch 26 near the central bent portion 20 is used. The horizontal width is set to be substantially the same as the width C only at the position where (FIG. 3) is formed. The end humidifying pieces 24aa and the end humidifying pieces 24ab are each formed with a first engagement hole 28 as a first attachment means. The first engagement hole 28 is a long hole substantially parallel to the section bending portion 22, and one end of the long hole is wide. One end humidifying piece 24aa is formed with an engagement slit 30 for engaging an insertion piece to be described later.

  In the humidifying element 18, if the two portions on the other end side divided into two at the central bent portion 20 are an end humidifying piece 24ba and an end humidifying piece 24bb, the end humidifying piece 24ba and the end humidifying piece The lateral width of 24bb is set to be narrower than the intermediate humidifying piece 24c. The end humidifying piece 24ba and the end humidifying piece 24bb are formed with a second engagement hole 32 as a second attachment means. A connecting piece 34 connected to the central bent portion 20 is provided adjacent to the end humidifying piece 24ba. For example, a semicircular cut line 36 is formed at the center of the connecting piece 34, and an insertion piece 38 is formed by the cut line 36. This insertion piece 38 is for engaging with the engagement slit 30 formed in the end humidifying piece 24aa. The insertion piece 38 is formed on the connecting piece 34 and the engagement slit 30 is formed on the end humidifying piece 24aa. However, the engagement slit is formed on the connecting piece 34 and the insertion piece is formed on the end humidifying piece 24aa. You may do it.

  The humidifying element 18 in the state shown in FIG. 3 is bent along the center bent portion 20, and the two bent regions are overlapped. A superposition of the two regions is made into a bellows shape that can be expanded and contracted by alternately bending a plurality of section bent portions 22 to the opposite side. Thereafter, the connecting piece 34 is bent toward the humidifying piece 24aa, and the insertion piece 38 of the connecting piece 34 is inserted into the engagement slit 30 of the humidifying piece 24aa. Thereby, the assembly of the humidifying element 18 is completed to obtain the humidifying element assembly 20 shown in FIG. 4, and this humidifying element assembly 20 is used. In the humidifying element assembly 20 shown in FIG. 4, one end of the humidifying piece 24 (the end humidifying pieces 24aa and 24ab and all the intermediate humidifying pieces 24c) excluding the end humidifying pieces 24ba and 24bb is bundled by the connecting piece 34. For this reason, if the connecting piece 34 is positioned below the liquid level in the container 12, water can be absorbed by a part of the end humidifying pieces 24aa and 24ab and one end of all the intermediate humidifying pieces 24c.

  As shown in FIGS. 1 and 2, the container 12 has an internal space 40 for storing a liquid therein, and one wall 42 in the longitudinal direction of the container 12 (a place far from the cover 14 when the cover 14 is opened). The wall on the side is an inclined wall that is inclined in a direction in which the internal space 40 is widened toward the upper opening end. As shown in FIGS. 2 and 5, the wall 44 of the container 12 facing the wall 42 (the wall on the side close to the lid 14 when the lid 14 is opened) has its center protruding outward. It has a square shape. That is, the wall 44 is composed of a front wall 44a on the front surface at both ends, a rear wall 44b in the center and a pair of parallel guide portions 44c that connect the front wall 44a and the rear wall 44b. A recessed space 46 is formed inside the rear wall 44 b and the pair of guide portions 44 c, and the recessed space 46 communicates with the internal space 40. As shown in FIG. 2, when the width dimension (inner wall interval) in the direction perpendicular to the longitudinal direction of the container 12 is A, the inner wall interval B of the pair of guide portions 44 c is shorter than A. Yes. The width B is set to be slightly larger than the width C of the intermediate humidifying piece 24c.

  As shown in FIGS. 1 and 2, two engagement arms 47 as first attachment means are formed on the inner bottom surface of the container 12, and one engagement arm 47 is the second of the end humidifying pieces 24 aa. One engagement hole 28 is engaged, and the other engagement arm 47 is engaged with the first engagement hole 28 of the end humidifying piece 24ab. A protrusion 48 is formed on the upper portion of the inclined wall 42 of the container 12 for locking with a locking portion of a lid, which will be described later.

  As shown in FIG. 1 and FIG. 2, two engagement arms 50 as second attachment means are formed on the inner surface of the lid 14, and one engagement arm 50 is the second humidification piece 24 ba of the end humidifying piece 24 ba. The other engagement arm 50 is engaged with the second engagement hole 32, and the other engagement arm 50 is engaged with the second engagement hole 32 of the end humidifying piece 24bb. A locking portion 52 is formed on the inner side surface of the lid 14 so as to lock and release the projection 48 of the inclined wall 42 of the container 12.

  As shown in FIG. 5, circular protrusions 54 are integrally formed on the outer sides of both side surfaces of the guide portion 44 c in which the recessed space 46 is formed on the inner side. A pair of arm portions 56 are integrally formed on the inner surface of the lid 14. The distance between the inner walls of the pair of arm portions 56 is set such that the both outer surfaces of the guide portion 44c can be sandwiched, and each arm portion 56 has a circular hole 58 that fits the circular protrusion 54. Is formed. The pair of arm portions 56 are opened, and the circular holes 58 formed in the arm portions 56 are fitted into the circular protrusions 54 formed in the guide portion 44c. As a result, the lid 14 can swing with respect to the container 12 around the protrusion 54 formed on the container 12.

  As shown in FIG. 5, a fitting portion 60 is formed at the center of the lower end of the inner surface of the lid 14. On the other hand, as shown in FIG. 6, a protrusion 62 is formed below the center of the outer surface of the wall 44 of the container 12. In the state of FIG. 6 in which the lid 14 is opened, the fitting portion 60 of the lid 14 is fitted with the protrusion 62 of the container 12, and the lid 14 is pushed downward by the protrusion 62. In the state where the lid 14 is opened, the lid 14 is held in a fixed position by pushing the lid 14 downward by the protrusion 62. When the lid 14 is opened, the lid 14 is not closed unless an external force is applied to the lid 14 in the direction of closing the container 12.

  The case where the humidification element 18 (FIG. 4) of the assembled state is attached to the container 12 and the lid 14 will be described. The container 12 and the lid 14 are opened, the first engagement hole 28 of the end humidifying piece 24aa of the humidifying element 18 is engaged with one engaging arm 47 of the container 12, and the end humidifying piece 24ab of the humidifying element 18 is engaged. The first engagement hole 28 is engaged with the other engagement arm 47 of the container 12. Further, the second engagement hole 32 of the end humidifying piece 24ba of the humidifying element 18 is engaged with one engaging arm 50 of the lid 14, and the second engagement hole 32 of the end humidifying piece 24bb of the humidifying element 18 is engaged. Is engaged with the other engagement arm 50 of the lid 14. Accordingly, the humidifying element 18 is attached to the container 12 and the lid 14 in a fan-shaped open state as shown in FIGS. 1 and 2. That is, all the humidifying pieces 24 of the humidifying element 18 are opened apart from each other.

  In the humidifier 10 of the present invention, the connecting piece 34 of the humidifying element 18 is positioned below the recessed space 46 of the container 12, so when water is introduced into the container 12, all the humidifying pieces 24 except for the humidifying pieces 24 ba and 24 bb. The connecting piece 34 in which one ends of the end humidifying pieces 24aa and 24ab and all the intermediate humidifying pieces 24c are bundled is immersed in water. As a result, the water in the container 12 can be moistened upward in a short time by capillary action on all the intermediate humidifying pieces 24c. The water is wetted through the intermediate humidifying piece 24c adjacent to the humidifying pieces 24ba and 24bb. In this invention, it has many humidification pieces 24, and since they are mutually separated, the humidification effect is high. Furthermore, since the humidifier 10 is compact because the humidifying element 18 can be accommodated in the case 16, it can be carried and installed at an arbitrary place.

  In a state where both ends of the humidifying element 18 are attached to the container 12 and the lid 14, the connecting piece 34 of the humidifying element 18 is arranged below the recessed space 46 formed by the rear wall 44 b and the pair of guide portions 44 c. The shape and dimensions of the humidifying element 18 are set. That is, one end of the plurality of intermediate humidification pieces 24c bundled by the connecting piece 34 is stored between the pair of guide portions 44c. Since the lateral width B of the recessed space 46 (interval B between the pair of guide portions 44c) is slightly larger than the lateral width C of the intermediate humidifying piece 24c, one end of the bundled intermediate humidifying pieces 24c is formed by the pair of guide portions 44c. The horizontal width direction is sandwiched so that the horizontal width direction does not substantially move. As a result, when the lid 14 is opened and closed, the lateral movement of the plurality of intermediate humidifying pieces 24 c is restricted by the guide portion 44 c of the wall 44, so that the humidifying element 18 can move in the opening and closing direction of the lid 14. Although it can, it does not move in the width direction of the container 12. Therefore, when the lid 14 is opened, the humidifying element 108 can be reliably opened in a fan shape in a stable state, and when the lid 104 is closed, the humidifying element 108 can be smoothly folded.

  The first engagement holes 28 of the end humidification pieces 24aa and 24ab that engage with the engagement arm 47 of the container 12 are formed in parallel with the moving direction of the lid 14. For this reason, when the lid 14 is opened and closed, even if the humidifying element 18 (end humidifying pieces 24aa and 24ab) moves in the opening and closing direction of the lid 14, the end humidifying pieces that engage with the engaging arms 47 of the container 12 The first engagement holes 28 of 24aa and 24ab move, and the engagement arm 47 does not come into contact with the ends of the first engagement holes 28 of the end humidifying pieces 24aa and 24ab. Therefore, when the lid 14 is opened and closed, there is no place where force is applied to the humidifying element 18 by the engaging arm 47, and the humidifying element 18 can be prevented from being damaged. Moreover, since there is no location where force concentrates on the humidifying element 18, the lid 14 can be opened and closed smoothly. In the above description, the first engagement holes 28 formed in the end humidifying pieces 24aa and 24ab that engage with the engagement arms 47 of the container 12 are long. The second engagement holes 32 formed in the end humidifying pieces 24ba and 24bb that engage with the arm 50 may be elongated.

  The wall 42 opposite to the attachment position of the lid 14 in the container 12 is an inclined wall that inclines in the direction of widening the internal space 40 toward the upper opening end. By pouring water into the internal space 40 of the container 12 from the inclined wall 42 side, water can be easily poured and the water splash can be prevented by contacting the humidifying element 18. Further, when water is discharged from the internal space 40 of the container 12, the water can be easily discharged from the inclined wall 42 side.

  In addition, the above-mentioned humidification element 18 showed what bent the half by the center bending part 20, and bent by the half by the some division | segmentation bending part 22 was shown. However, without being folded in half, the plurality of humidified pieces 24 are formed alternately by the plurality of section bent portions 22 as they are, and the first first engagement holes 28 are formed in the humidified pieces on one side, You may make it form the 2nd 2nd engagement hole 32 in the humidification piece of the side.
