Abstract

PURPOSE:To obtain the title deodorizing filter wherein the deodorizing body can be easily handled by laminating respectively a fibrous member with deposited porous ceramic particles impregnated with a deodorant and a fibrous member with deposited activated carbon particles. CONSTITUTION:The first filter 2 is obtained, for example, by depositing porous ceramic particles 8 impregnated with a deodorant on the fiber 6 of an air- permeable member 5 of foamed urethane, unwoven fabric, etc. having three- dimensional fibrous structure with an adhesive 7. The second filter 3 is obtained by depositing activated carbon particles 9 on the fiber of an air-permeable member 5 having the same structure as the first filter. Since each particle 8 and 9 is deposited on the fiber 7, the air permeability of the air-permeable member is maintained. The first and the second filters 2 and 3 are bonded to each other with an adhesive, and encased freely detachable in a vessel 1 provided with many air holes 4.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a deodorizing filter applied to an air purifier or the like.

[Background technology]

A conventional deodorizing filter has a deodorizing body made of a large number of solid particles placed in a breathable container. However, there is a drawback that handling is complicated due to the particles, and the container is wasted because it is necessary to replace the container when replacing the deodorizer.

[Purpose of the invention]

An object of the present invention is to provide a deodorizing filter whose container can be reused and whose deodorizing body is easy to handle.

[Disclosure of the invention]

The deodorizing filter of the present invention includes a first filter in which the fibers of a breathable member having a three-dimensional fiber structure are coated with porous ceramic particles impregnated with a deodorizing agent, and a first filter that is the same as the breathable member. and a second filter in which activated carbon particles are attached to the fibers of the breathable member of the structure. Each particle is fixed in the air-permeable member at 7°, making it easy to handle, and since the filter can be easily attached to and removed from the container, the container can be reused when replaced.

Embodiment An embodiment of the present invention will be explained based on FIGS. 1 to 9. In the figure, 1 is a container, 2 is a first filter, 3 is a second filter, the first and second filters 2.3 are mutually bonded with adhesive, and a large number of ventilation holes 4 are provided. It is housed in a container 1 in a detachable manner. 1st
The filter 2 is made by attaching porous ceramic particles 8 impregnated with a deodorant to the fibers 6 of a breathable member 5 having a three-dimensional fiber structure such as urethane foam or non-woven fabric using an adhesive 7.
j# I'm doing it. The second filter 3 has activated carbon particles 9 attached to the fibers of a breathable member 5 having the same structure as the above. In this case, since the particles 8 and 9 are attached to the fibers 7, the air permeability of the iIB air member 5 is ensured.

No. 61. A shows how these filters are manufactured.

The upper stage shows the manufacturing process of the second filter 3, in which the breathable member 5 is immersed in an adhesive bath 10, and then in an activated carbon particle bath 1.
Then, only one side is immersed in the adhesive bath 12.

-1st stage is the manufacturing process of the first filter 2, in which the breathable member 5 is immersed in the adhesive bath 1O as described above, and then immersed in the porous ceramic particles 13 impregnated with a deodorizing agent in advance. , one side is immersed in an adhesive bath 12, and one side of the first filter 2 is polymerized and bonded to that one side. According to this manufacturing method, the first filter 2 and the second filter 3 are integrated, making it easier to use.

FIG. 7 shows this deodorizing filter A applied to an air purifier. In the figure, 14 is a fan casing having a hanging metal fitting, 15 is a motor, 16 is a fan, 17 is a suction port grill plate, 18 is a discharge port, and a fill filter 19 is provided inside the suction port grill plate 17. A filter block accommodating chamber 20 is formed inside thereof, and a filter block 21 is accommodated in this accommodating chamber 20. A deodorizing filter A is placed overlapping this filter block 21. When the fan 16 rotates due to the operation of the motor 15, wind enters through the intake grille plate 17, and the blur filter 19.
It is cleaned by the filter block 21 and further deodorized by the deodorizing filter A.

The air that has passed through the deodorizing filter A is discharged from the discharge port. The deodorizing filter A is replaced by removing the screws 22 and the suction grill plate 17.

Furthermore, FIG. 8 shows another manufacturing example of the deodorizing filter A. That is, the entire breathable member 5 is placed in the adhesive tank 10.
After that, half of the thickness of the breathable member 5 is immersed in the activated carbon particle tank 11, and the other side is immersed in the ceramic particle tank 1.
Manufactured by soaking in 3.

The deodorizing filter A thus produced is shown in FIG.

This method eliminates the need for a polymerization bonding step.

With this configuration, when replacing the deodorizing filter A, it is only necessary to replace the first and second filters 2.3, and the container 1 can be reused. In addition, handling at the time of replacement is easier than when the activated carbon particles 9 and porous ceramic particles 8 are arranged in a granulated structure and housed in a cake.

〔Effect of the invention〕

According to this invention, since the deodorizing particles are attached to the fibers of the breathable member, it is easy to handle and the container can be reused even when replaced.
