DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purifying filter capable of removing dirt and dust in the air, as well as odors and harmful substances. C
The present invention relates to an air purifying filter that can be used for electronic devices such as PUs and printers.Furthermore, separately from the filters provided inside these devices, they can be easily attached to the outside of the device, optionally. The present invention relates to a removable air purifying filter.

[0002]

2. Description of the Related Art There are air conditioners, such as air conditioners and fan heaters, which suck air and cool it or warm it and discharge it again. These air conditioners suck dust together with dust and dirt in the air when sucking air, so the dust and dirt adhere to the machine inside the device and generate mold or damage the machine. That accident had occurred. In order to prevent such an accident, a filter for removing dust and the like in the air is usually provided inside. Further, it is necessary for a computer CPU, a printer, a copying machine, or the like to take in air in order to cool an IC, which is a component. Even in these devices, dust in the air and the like may cause mechanical failure or shorten the life of components, but in reality, few have taken such measures, and it has been desired to take countermeasures.

[0003]

An air conditioner such as an air conditioner includes a filter for removing dust and the like in the air at an intake port for taking in indoor air. These filters are generally of a general-purpose type that is used again after removing accumulated dust with a vacuum cleaner or the like.
With these filters, garbage that could not be removed by the vacuum cleaner was discharged into the room again, and regular replacement was necessary from a sanitary point of view. However, these filters are dedicated filters conforming to the model standards of the manufacturers, and the filters themselves are sold at high cost, so that the maintenance cost is extremely high. In the case of an exchange-type filter that is replaced every time dirt accumulates, such a problem of cost is further increased. Filters also have improved cleaning capabilities, but filters used in older air conditioning equipment still have poor cleaning capabilities. You cannot expect the same level of cleaning ability.

[0004] Another problem to be solved by the present invention is:
It is troublesome for maintenance. As mentioned above, it is necessary to replace the filter at any suitable time or to clean the filter itself, but since it is inside the equipment,
It is difficult to check the dirt condition. It was not uncommon for equipment to be left unnoticed and damaged until it was damaged. In addition, the replacement is troublesome because it is inside the device. Especially for large air conditioners, their replacement requires specialized knowledge, so it is necessary to call a specialized contractor for replacement. In addition, since the filter is inside the device, dust accumulates in the slit of the air inlet of the air conditioner, but it is difficult to remove dust and the like in the narrow slit.

[0005] Further problems to be solved by the present invention are:
It is an issue of cleaning ability. As the conventional filter described so far, non-woven fabric or paper to which fibers are adhered is used as it is, and by passing through it, the dust and dirt in the air are removed by filtering the fibers. Was. However, what can be removed with such a filter is garbage and the like that can be seen at best, and it is impossible to remove finer objects and harmful substances in the air.
For example, it is impossible to remove the odor in the air, and it has not been possible to remove gaseous fine substances such as formaldehyde, which has recently been talked about as a harmful living gas. Also, pests such as mites, which can only be seen with a microscope, could easily pass through the filter and fly back into the room.

The problems described so far mainly relate to air conditioners such as air conditioners, but these problems also apply to electronic devices such as CPUs and printers of computers. Many of these electronic devices did not have a filter inside, and even if they were attached, most of them were poor in that the sponge-like thing covered the air intake from the inside.
However, components such as an IC board used in these electronic devices are such that a circuit is short-circuited only by the attachment of small dust, and the dust often causes malfunction. In addition, the smoking of cigarettes in the office also stains the inside of the device and causes a malfunction, and these poor filters have never been sufficient. As a problem of maintenance, it is impossible to easily look inside the electronic device, and it has been almost impossible to check and replace the filter for dirt.

The present invention relates to a filter which can be widely used not only for air conditioning equipment such as an air conditioner but also for electronic equipment such as a computer, and which is externally attached to an air intake port separately from a filter installed inside the equipment. The purpose is to provide an air purifying filter that can remove not only garbage and dust in the air, but also odors and fine substances, and that is easy to maintain, such as checking and replacing dirt. It is assumed that.

[0008]

The air purifying filter according to the present invention uses activated carbon, charcoal, bamboo charcoal or the like as a filtering material to remove odors and fine substances in the air. The above object is achieved by allowing a filter including a filter material or a filter including a filter material to be attached to and detached from the outside of the device.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the air purifying filter according to the present invention is one in which a filtering material for filtering air is sandwiched between a plurality of cloth-like fibrous materials such as nonwoven fabric and paper. The cloth-like fiber material may be a cloth such as a thin gauze. Activated carbon, charcoal, bamboo charcoal, and the like can be used as the filtering material. These are usually granular, and many of them are used. When sandwiched between fiber materials, it is conceivable to attach the filter material to the fiber material with an adhesive so that the filter material sandwiched inside does not accumulate below, but so as not to hinder the flow of air with the adhesive, for example, It is conceivable to divide the interposed space into a plurality of parts by bonding a plurality of places in parallel or sewing with a thread or the like. One or a plurality of fixing means for attaching to the outside of the device is attached to one surface of such a fibrous material. As the fixing means, an adhesive such as a double-sided tape may be used, or a magnet may be adhered to one surface if it is attached to a steel device, or a sucker-type fixing means may be used. Alternatively, it may be a velcro tape attached to the filter side and the device side facing each other. Alternatively, a clip formed of plastic or the like to be hooked on the slit of the air intake port of the device may be bonded.

As described above, the filter material sandwiched between the fibrous materials may be housed in a case. As the material of the case, various materials such as plastic and paper can be used, and as the paper, a hard material such as corrugated paper is preferable from the viewpoint of strength. This is folded and formed into a box shape, and a large number of slit-shaped air circulation portions are formed on both surfaces. As the air circulation portion, a shape in which the center of the box is largely hollowed out, that is, a case in which the center is almost penetrated and only a square frame like a picture frame can be used. The fiber material sandwiching the above-mentioned filter material is stored therein. The same fixing means as described above is attached to one surface of the case.

In some cases, instead of sandwiching a multiparticulate filter material between fibrous materials, it is stored in a case as it is. That is, the filter medium is stored as it is in a case having a fine air circulation portion such as a slit or a mesh. In such a case, a net material having a fine mesh is effective as a case.

Instead of a multiparticulate filter material, a mat-type filter material obtained by molding a synthetic resin fiber with a filter material adhered to the periphery thereof into a mat shape can also be used. The synthetic resin fiber used is a synthetic resin fiber such as polyethylene or polystyrene, and a fine filter material is directly attached to the fiber. These fibers are attached to a non-woven fabric and formed into a mat having a thickness of about several millimeters. A reinforcing plate is adhered to both sides or one side of the mat-shaped filter medium. The shape of the reinforcing plate may be one in which a plurality of slits, which are air circulation portions, are formed on the plate surface, or may be a square frame-like plate having a large opening at the center as the air circulation portion. A fixing means is attached to this reinforcing plate.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings. 1 to 4, reference numeral 1 denotes a case in which corrugated cardboard is formed into a thin box shape, and an air circulating portion 2 which is a large number of slits is formed on both sides. A multiparticulate filter material 4 is sandwiched by the cloth-like fiber material 3 in the internal space of the case 1. A nonwoven fabric made of synthetic resin fibers is used as the cloth-like fiber material 3, and activated carbon is used as the filter material 4. A plurality of portions of the cloth-like fiber material 3 are bonded in parallel and linearly by heat welding, and a space between the cloth-like fiber materials 3 is partitioned. The filter media 4 are stored in the partitioned spaces, and the filter media 4 does not accumulate below. On one side of the case 1, double-sided adhesive tapes 5 as fixing means are attached at four corners.

Such an air purifying filter is installed in front of the air inlet 7 of the indoor unit 6 of the air conditioner. That is, the air purifying filter of the present invention is newly attached separately from the filter already provided inside the air conditioner. Since the double-sided adhesive tape 5 is previously bonded to a desired position of the indoor unit 6, it may be used so as to cover the air intake port 7 of the indoor unit 6. The fixing means may be attached to the filter side in advance, or may be fixed at a place where it is attached in this manner. If one filter is not enough, install multiple filters side by side. As described above, since the air purifying filter according to the present invention is attached to the outside of the device, it is easy to check the degree of contamination.
Installation and removal are extremely easy. In addition, filter media 4
Can adsorb and remove odors and toxic gases in the air, and can also remove fine mites, thus significantly improving the cleaning ability. Furthermore, it is not standardized for each maker, but is manufactured at low cost and easily available to consumers.

In the embodiment shown in FIGS. 5 and 6, a multi-filamentary filter material 4 is sandwiched between a plurality of fibrous materials 3 and the double-sided adhesive tape 5 is also used on one side. Multiple are bonded. Such an air purification filter is used in the same manner as described above, but is suitable for use outside a relatively small air inlet, for example, in electronic equipment.

FIG. 7 shows an example in which a mat-shaped filter medium 8 in which a filter medium is directly attached to a fiber is used. Around each relatively thick synthetic resin fiber, a filter medium such as activated carbon is rubbed and attached like a non-woven fabric. It has a rigid mat shape of millimeters. A reinforcing plate 9 made of corrugated paper is attached to both sides of the mat-shaped filter medium 8. The reinforcing plate 9 has a plurality of slits 1 serving as air circulation portions.
0 is formed. On one side of the reinforcing plate 9, mounting members 11 as clip-like fixing means are mounted at four corners. The attachment 11 is made of plastic, and two elastic beak-shaped hooking pieces 13 protrude from the plate-like bonding portion 12. The adhesive portion 12 is fixed to the reinforcing plate 9 with a double-sided adhesive tape 14, and the hook 1
3 is hooked and attached to a slit of an air inlet 7 of an air conditioner. The hook 13 is hooked and attached to the slit by the elasticity of the hook 13. FIG. 9 shows another embodiment of the fixture 15, in which a U-shaped holding piece 17 which is bent into two from a fixing portion 16 projects. The bar of the slit is sandwiched by the holding pieces 17 and attached. The fixing portion 16 may be fixed with a double-sided adhesive tape, a magic tape, or a suction cup. FIG. 8 shows a structure in which a reinforcing plate 9 is fixed to only one surface of the mat-shaped filter medium 8, and the reinforcing plate 9 has a frame-like shape in which only the peripheral end is reinforced and the center is a large air circulation portion. doing. Such a reinforcing plate 9 can be manufactured at lower cost.

[0017]

Since the present invention has the above-described configuration, the following effects can be obtained. In addition to fibrous materials, it also contains activated carbon and other filtering materials, so it absorbs odors in the air, fine dust and debris, toxic gases, and small harmful insects such as mites. It is very effective in health and hygiene.
It is easy to attach such an air purifying capability to the outside by attaching it to the outside of an old type air conditioner. Since it is of a type that is attached to the outside instead of the inside of the device, it is easy to check the degree of dirt and the attachment / detachment work is also easy. Also, the number of replacements of the existing filters inside the device is significantly reduced, so that maintenance work can be significantly reduced. In addition, cleaning of the air intake of the air conditioner and the like is significantly reduced. Unlike dedicated filters for equipment, it is versatile and can be manufactured at a lower cost, so both costs and maintenance costs are lower. It can be easily attached to electronic devices or the like that do not have a filter in the past, and these devices can prevent failure caused by dust and fine particles. Air-conditioning equipment is installed outside the air intake, so the use of air intake and exhaust functions eliminates the need for a dedicated power supply or motor, and is unprecedented, as is the case with a separate air purifier. Cleaning ability can be added. Since it is attached to the outside of the device by the fixing means, it does not need to be installed on a floor, a shelf, or the like. In addition, there is no wiring code, and no accidents caused by children's mischief occur. Since it is an inexpensive replacement type filter, dust and odor once removed by being discarded can be completely removed from the device, and dust does not return to the room again. If a filter material is attached to the fiber, it is easy to manufacture, and can be provided at low cost without using a case. By using a clip-shaped mounting tool and hooking it to a slit of an air intake port of an air conditioner or sandwiching a bar, the surface of the device is not stained with an adhesive or the like.
