An air purifier is known which sequentially disposes air from a room through a dust collecting filter and a deodorizing filter by driving a blower to drive the air from a suction port into a main body case through a dust collecting filter and a deodorizing filter. ing.

[0003] Such air purifiers can purify efficiently using both a dust collecting filter and a deodorizing filter when the air in the room to be purified is contaminated by dust and odor. If only the filter is dirty, or if it is mainly stained with odor, one filter is mainly used, the other filter is hardly used, and a loss is caused by the pressure loss of the other filter, The efficiency was getting worse.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an air purifier which can efficiently purify the air in a room even if the air becomes dirty.

[0005]

A first means for solving the above-mentioned problem is that air sucked into the main body by driving a blower is supplied to a dust collecting filter and a deodorizing filter which are detachably provided in the main body. In an air purifier that performs dust collection and deodorization by passing through, a dust collection filter can be provided instead of the deodorization filter.

Accordingly, when the air in the room to be purified is contaminated with dust and odor, dust collection and deodorization can be efficiently purified by both the dust collecting filter and the deodorizing filter, and the dust is mainly contaminated with dust. In this case, another dust collecting filter is provided in place of the deodorizing filter which is hardly used at this time, so that the dust can be intensively removed by the two dust collecting filters.

[0007] A second means for solving the above problems is as follows.
In an air purifier that removes dust and deodorizes by passing air sucked into the main body by driving a blower to a dust collection filter and a deodorization filter that are detachably provided in the main body, instead of the dust collection filter A filter can be deployed.

Accordingly, when the air in the room to be purified is contaminated with dust and odor, dust collection and deodorization can be efficiently purified by both the dust collecting filter and the deodorizing filter, and the air is mainly contaminated by odor. In this case, by disposing another deodorizing filter in place of the dust collecting filter which is hardly used at this time, the odor can be intensively removed by the two deodorizing filters.

[0009] A third means for solving the above problems is as follows.
In an air purifier that performs air collection and deodorization by driving a blower to a dust collection filter and a deodorization filter, which are detachably disposed in the main body, the dust collection is performed instead of the deodorization filter. Filter
A deodorizing filter can be provided instead of the dust collecting filter.

Accordingly, when the air in the room to be purified is contaminated with dust and odor, dust collection and deodorization can be efficiently purified by both the dust collection filter and the deodorization filter, and the dust is mainly contaminated by dust. In this case, by installing another dust collecting filter in place of the deodorizing filter that is hardly used at this time, the dust can be intensively removed by the two dust collecting filters, and when dust is mainly contaminated by odor, In this case, by disposing another deodorizing filter instead of the dust collecting filter that is hardly used at this time, the odor can be intensively removed by the two deodorizing filters.

[0011] In the above structure, a storage recess is formed in the main body in which both the dust collecting filter and the deodorizing filter can be stacked, and the storing recess is formed in the depth of the depth of the deodorizing filter and the dust collecting filter. Deep filter 2
It is a depth that can store the months.

Thus, both the dust collecting filter and the deodorizing filter can be provided in the storage recess, or two filters can be provided in place of one filter without providing a separate storage part. can do.

It is desirable that the pressure loss caused by the dust collecting filter and the pressure loss caused by the deodorizing filter be substantially the same.

With this arrangement, when two filters are installed instead of one filter, the pressure loss caused by the filters hardly differs from the case where both a dust collecting filter and a deodorizing filter are installed. The load and the amount of air blow hardly change, and stable air blow can be performed.

FIG. 1 to FIG. 5 show an embodiment of the present invention, and a description will be given with reference to these drawings.

The air purifier main body case 1 includes a front cover 2
An outer shell is formed from a cover 4 on which a grill-shaped discharge port 3 is formed on one side of the upper surface and an upper cover 7 on which various operation buttons 5 and a display unit 6 are formed. On the front cover 2,
A large lattice-shaped opening 10 is formed in the front cover 2 so that an intake plate 9 having a large number of holes 8 serving as intake ports is mounted on the entire surface, and outside air is sucked into the main body through the holes 8. Have been.

The inside of the main body case 1 is partitioned forward and backward by a partition plate 11, and a filter device 12 for collecting and deodorizing air is built in between the partition plate 11 and the front cover 2, and the partition plate 11 and the rear cover are provided. A blower 15 including a motor 13 and a fan 14 rotated by the motor is built in between the four. The motor 13 is mounted on the partition plate 11. The periphery of the fan 14 is surrounded by a spiral fan casing 16 projecting integrally from the rear cover 4, and the inside of the fan casing 16 communicates with the discharge port 3.

When the blower 15 is driven, the outside air is sucked through the holes 8, and the sucked outside air is collected and deodorized by the filter device 12 and purified, and passes through the fan casing 16. It is discharged from the discharge port 3.

The filter device 12 includes a dust collecting filter 18 and a deodorizing filter 19.

The dust collecting filter 18 is formed by processing an electretized polypropylene nonwoven fabric into a fold and folding the periphery thereof to a paper frame.

The deodorizing filter 19 comprises a first deodorizing layer comprising cellulose beads 22 impregnated with polyphenols, a second deodorizing layer comprising a nonwoven fabric layer 23 which impregnates citric acid and chemically deodorizes ammonia, and paper. A third deodorizing layer formed by accommodating activated carbon particles 24 in a large number of small chambers 30 of the honeycomb-shaped structure formed by the above, and a paper frame 25 for fixing the outer periphery of the first to third deodorizing layers And the depth is smaller than that of the dust collecting filter 18. The activated carbon particles 24 are composed of a plurality of types in which components corresponding to each of a basic gas, a neutral gas, and an acidic gas are impregnated.

In this deodorizing filter 19, the ventilation resistance is adjusted by the density of the activated carbon particles, and the pressure loss when air passes through is substantially the same as the pressure loss of the dust collecting filter 18 (here, the pressure loss of the dust collecting filter 18 is different from the pressure loss of the dust collecting filter 18). The difference is within plus or minus 25 percent).

Deodorizing filter 19 and dust collecting filter 18
Is a storage recess 26 formed by recessing the partition plate 11 on the back side.
The deodorizing filter 19 is housed inside so as to be on the leeward side. The storage recess 26 has such a depth that two dust collection filters 18 having a large depth can be arranged in layers (here, the depth is such that the dust collection filter 18 does not come off even if it is not completely inserted). Thereby, two dust collecting filters 18 can be stored in place of the deodorizing filter 19 without separately providing a part for storing (the state of FIG. 4), and two deodorizing filters 19 can be used instead of the dust collecting filter 18. It can be stored (the state of FIG. 5).

The front cover 2 has a large lattice-shaped opening 10.
, A suction plate 9 covering the opening 10, and a pre-filter 28 provided on the back side of the suction plate 9. The pre-filter 28 removes coarse dust before the filter device 12 collects and deodorizes the dust.

Push buttons 2 are provided on both left and right sides of the frame 27.
A locking claw (not shown) that is removably locked to the partition plate 11 by the operation 9 is formed.

When the air purifier having the above configuration is used in a place that is contaminated with dust and odor, the dust collecting filter 18 and the deodorizing filter 19 are provided in the storage recess 26 as shown in FIG. When the blower 15 is driven, the air in the room sucked into the main body case 1 from the hole 8 passes through the dust collecting filter 18 and the deodorizing filter 19 sequentially, and both the dust collecting and the deodorizing are performed. It is returned into the room from the outlet 3 again.

When the filter is used in a place mainly contaminated with dust, such as asbestos powder, a dust collecting filter 18 is provided instead of the deodorizing filter 19 as shown in FIG. When the blower 15 is driven, the air in the room sucked into the main body case 1 from the hole 8 sequentially passes through the two dust collection filters 18 and 18, and after the dust is collected, the room is again discharged from the discharge port 3. Will be returned within. On this occasion,
Dust in the air is collected by the dust collection filter 18 on the upstream side (suction side) and then further collected by the dust collection filter 18 on the downstream side, so that more dust is removed and the dust collection efficiency is improved. improves.

When used in a place mainly contaminated with odors such as volatile organic compounds (VOC), a deodorizing filter 19 is provided instead of the dust collecting filter 18 as shown in FIG. When the blower 15 is driven, the room air sucked into the main body case 1 through the hole 8 sequentially passes through the two deodorizing filters 19, 19, and only the deodorizing is performed. Is returned to.
At this time, the odor in the air is deodorized by the deodorizing filter 19 on the upstream side (suction side), and is further deodorized by the deodorizing filter 19 on the lower side, so that more odor is removed and the deodorizing efficiency is improved. .

As described above, by changing the combination of the dust collecting filter 18 and the deodorizing filter 19 according to the state of dirt in the room, it is possible to efficiently purify the dirt even if the state of dirt changes.

Further, by making the pressure loss of the dust collecting filter 18 and that of the deodorizing filter 19 substantially the same, the deodorizing filter 19 can be provided instead of the dust collecting filter 18 as shown in FIG. Deodorizing filter 19
When the dust collection filter 18 is provided in place of the above, the pressure loss due to the two filters can be made substantially the same as when both the dust collection filter 18 and the deodorization filter 19 are provided. Therefore, compared with the case where both filters are provided, the load applied to the motor 13 of the blower 15 hardly changes, and the air volume can hardly change.

Accordingly, at this time, the pressure loss due to the two filters is reduced, and the wind volume is increased to increase the wind noise, or conversely, the pressure loss is increased, and the motor 13
This can prevent the noise generated by the motor 13 from increasing due to an increase in the load applied to the motor 13, and can always perform quiet and comfortable driving.

In the above embodiment, the dust collection filter 18
And the deodorizing filter 19, so that they are arranged in layers,
Although either one of the two filters can be installed instead of the other filter, the dust collection filter 18 and the deodorizing filter 19 are arranged side by side without being overlapped, and one of the two filters is replaced with the other filter. And may be deployable.
