Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a storage case that accommodates a humidifying element wound in a spiral shape and that is easily assembled.

[0002]

[Prior art]

 As a moisture-permeable membrane type humidifying element wound in a spiral shape, there is a humidifier described in JP-A-60-17133.7.

The humidifier has a hollow body made of a hydrophobic porous material, a spacer for forming a water channel inside a hollow body, a long flat bag having a water supply port at one end, and a wavy shape for forming a ventilation channel. A cylindrical or elliptical element 4 which is wound in a spiral shape together with the spacing member is used.

However, since the element 4 as it is expands due to the water supply pressure, it is necessary to prevent the expansion by putting it in a storage case that retains its shape.

In a conventional storage case, as shown in FIGS. 5 and 6, a square frame-shaped case 3 is formed by screwing a U-shaped frame 1 made of a metal plate and a lid 2 also made of a metal plate. A plastic corner spacer 5 is inserted in the gap between the four corners of the case 3 and the outer circumference of the element 4 to maintain the shape of the element 4.

Further, when water is supplied to the element 4, the porous hollow body expands to cause a displacement, and the element 4 does not protrude beyond the inside of the case 3 when the case 3 falls, so that a main part of the case 3 is prevented. It was necessary to attach a stopper 6 to prevent the metal wire from being bent.

[0007]

[Problems to be Solved by the Invention] A conventional storage case has a complicated structure composed of a large number of parts as described above, and requires complicated work such as pressing a metal plate or bending a metal wire. However, there is a problem that laborious work such as screwing is required even when assembling.

In order to solve the above problems, an object of the present invention is to provide a housing case that has a simple structure, a small number of parts, and is easy to manufacture and assemble.

[0009]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention uses a synthetic resin housing for the humidifying element, which has a water supply port at one end and a discharge port at the other end, and encloses the outside of the humidification element. It consists of a frame and a porous displacement prevention frame that prevents displacement of both ends of the humidification element.One of the prevention frames is a square, and the whole of the square prevention frame is axially divided along the side frame from the diagonal line of the prevention frame. The case is divided into two case members of substantially the same shape, and a structure is provided in which a detachable connecting means for connecting the case members together is provided.

[0010]

[Action]

 The humidifying element, which is wound in a spiral shape and has a water inlet at one end and a discharge outlet at the other end, is covered with a case member of the same shape divided into two parts of the storage case of the present invention, and its opposite part is contacted. The humidifying element of the moisture permeable membrane type is completely housed in the housing case by connecting the connecting means of the facing portion.

[0011]

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 3, reference numeral 11 is a sheet made of a hydrophobic porous material. The sheet 11 is made into two sheets by sandwiching a flexible spacer 12 around the sheet, and a water supply port 13 is provided at one end and a discharge port 14 is provided at the other end. A flat hollow body 15 provided with is formed.

Then, for example, as shown in FIG. 4, by sandwiching a corrugated spacing member 16 made of plastic, the hollow body 15 is spirally wound to form a cylindrical or elliptical moisturizing membrane type humidifier. Create element 17.

Reference numeral 18 in FIG. 1 is a storage case for the humidifying element. This storage case is made of synthetic resin, and has two side frames in which a cylindrical shape or an elliptic cylinder shape surrounding the outer periphery of the element 17 is divided into two halves around the axis thereof. A displacement prevention frame 21 having a large number of holes 20 for holding one end of the humidifying element 17 is provided at one end of 19, and a large number of holes 22 for holding the other end of the humidifying element 17 are also provided at the other end of the same side frame 19. A displacement prevention frame 23 is provided, and a pair of case members 25 are formed on the outside of the prevention frame 23 by integrally providing an outer frame 24 that is formed by dividing a quadrangle into two by diagonally dividing it into three shapes. .

Then, the convex portions 26 and the engaging holes 27 are provided on the opposing surfaces of the both case members 25, so that the case members 25 can be coupled and separated by engaging and disengaging them. Further, a notch 29 for taking out the water supply port 13 of the humidifying element 17 and the discharge port 14 is provided at a part of the outer frame 24.

In the case of the above-described embodiment, the side frames 19 of both case members 25 surround the outside of the humidification element 17, and both ends of the humidification element 17 are covered with the displacement prevention frames 21 and 23 at both ends, so that both case members 25 are covered. The projections 26 on the surfaces facing each other are engaged with the engagement holes 27.

Further, the water supply port 13 drawn out from the element 17 is drawn out from the notch 30 for extraction and connected to a connection joint 31 attached to the notch 29, and the joint port on the opposite side is connected to a water supply tank (not shown). . The outlet 14 is closed.

As described above, in the storage case 18 in which the humidifying element 17 is stored, the displacement preventing frames 21 and 23 at both ends thereof are provided with a plurality of large holes 20 and 22, respectively, so that the water in the water supply tank is supplied from the water supply port 13 to the element. When the dry air is discharged from one of the holes 20 1 through the gap of the humidifying element 17 to the other hole 22 while supplying water into the inside 17, the moisture oozing from the humidifying element 17 provides the air with an appropriate humidity. The outlet 14 is used for draining water or for removing water scale by circulating water.

[0019]

[Effect of device]

 As described above, the present invention has a much simpler structure than the conventional metal plate case because the humidifying element storage case consists of a pair of case members made of synthetic resin. Since both storage cases have the same structure, it is extremely easy to mold and suitable for mass production.

Further, since the side frame surrounding the outside of the humidifying element and the shift prevention frame of the humidifying element are integrated, there is no fear that the porous hollow body will expand and shift when water is supplied to the humidifying element. Even if the case falls, the humidifying element does not stick out of the case.
