Description

[Detailed description of the invention] [Field of industrial application] This invention is applicable to an air purifier that cleans dirty indoor air, that is, dirty air that contains dust particles such as pollen, bacteria, and cigarette smoke. It depends.

[Conventional technology] Indoors, dust particles harmful to the human body such as cigarette smoke, bacteria, mold, and cotton dust, as well as mites and their eggs on floors and carpets, float in the air. ing.

Therefore, air purifiers are used to remove these dust particles.

FIG. 4 is a perspective view showing an example of the device, which can be used both on the floor and on the wall.

That is, in this cleaner 40, a panel 42 having a suction port 41 formed in the front surface is detachably attached to the casing of the cleaner 40. Then, the panel 42
A filter 43 is housed in a groove formed inside the panel 42, and is held in the groove of the panel 42 so that it can be replaced when the filter 43 becomes dirty and its cleaning power reaches its limit.

Further, inside thereof, there is a rotary blade 47 driven by an electric motor 45 having a drive shaft 44 disposed perpendicularly to the front panel 42, and having a large number of fins 46 disposed on the circumference. Installed as shown.

On the other hand, an air outlet 48 and a slide switch 49 are provided on the upper surface of the housing C.

However, when slide switch 49 is turned on,
Air is sucked into the casing C by the rotary blade 47 from the intake port 41 on the front surface.

Then, when passing through the filter 43, the dust particles etc. adhere to the filter 43,
Only purified air passes through the filter 43.

The air that has passed through the filter 43 is sent to the rotary blade 47
As a result, the air is forcibly supplied from the upper air outlet 48.

Although not shown, the filter 43 has a multilayered shape in which three to four layers of fiber materials such as glass fibers are stacked.

For example, antibacterial filters that are coated with chemicals to prevent the growth of mold and bacteria, deodorizing filters that are coated with activated carbon to eliminate cigarette and pet odors, and charged layers that are coated with cotton dust and 0.3 to 10 micron cigarette smoke. A charged filter that attaches and collects fine particles such as particles by the action of static electricity is laminated together.

When the filter 43 becomes dirty and its cleaning power deteriorates, the front panel 42 is removed and the filter 43 attached to the back is replaced with a new one.

Therefore, the cleaner 40 takes air into the housing from the side and supplies it to the upper part of the housing.

On the other hand, in cases where the entire building is air-conditioned, such as in a rental building or a hospital, a building air-conditioning system as shown in FIG. 6 is often adopted.

That is, the circulation mechanism 61 disposed in the air-conditioned room 60 provided in one corner of the building B sucks air from the room R and supplies purified air again.

Air is filtered as it passes through filters placed inside the supply and air outlets of each room and the filters of air conditioning equipment.

The air outlet 62 of the circulation mechanism 61 is arranged near the ceiling, while the inlet 63 provided with a marshmallow-shaped umbrella is arranged on the floor.

Therefore, air is taken in from the floor and duct 6
4 to the air conditioned room 60, and again through the air outlet 6.
It is supplied indoors from 2.

[Problems with the prior art] In the first conventional example, air is taken in from the side (front) of the purifier, so it is difficult to remove insect bodies such as mites that stay on the floor. Ta.

In addition, in the second conventional example in which the inlet is placed on the floor, the inlet is fixed to the floor, and therefore,
Not only can they not be moved to other places, making it impossible to freely arrange the layout of the room, but even though insect bodies near the inlet are removed, particulate insects floating in the air circulating indoors can be removed. It was difficult to remove the body.

[Means for solving the problem] The present invention forms an air outlet in the upper part of the housing, and arranges a suction inlet and a caster in the bottom of the lower part, and a net-like plate is installed in the housing inside the suction inlet. A rotor blade in which a secondary filter made of a filter, a glass fiber, etc., and a tertiary filter made of a Hepa filter, etc. are sequentially arranged, and air is guided from below to above to a bracket attached between the pre-filter and the secondary filter. This air purifier is characterized by being equipped with an electric motor equipped with.

[Function] The present invention uses rotary blades driven by an electric motor to forcibly suck in air from the bottom of the purifier, and a prefilter placed just inside the suction port. Coarse dust particles and insect bodies such as mites that accumulate on the floor surface adhere to the prefilter.

Next, a secondary filter disposed above the electric motor successively removes dust particles and insect bodies finer than those adhering to the pre-filter.

Furthermore, the Hepa filter, which is a high-performance filter often used in clean rooms, is placed at the top, and sterilized clean air is sent into the room from the outlet.

In addition, casters placed on the bottom of the housing allow it to be moved freely within the room, making it possible to use it at any location.

Needless to say, it also inhales and cleanses fine particles such as dust and cigarette smoke, as well as fungi such as mold and bacteria that are circulating and floating in the air inside the room.

[Example] Fig. 1 is a perspective view showing the air cleaner of the present invention, Fig. 2 is a longitudinal sectional side view of the same, and Fig. 3 is a transverse sectional view of the same.

The casing 2 of the air purifier 1 has a so-called wagon shape, and has an inclined surface 5 cut along the ridgeline of the top plate 3 and the front plate 4, and a grill-shaped blowout is formed on this inclined surface. An outlet 6 is provided. In addition,
Similar air outlets 7 may be provided on both sides of the air outlet 6, or a shutter may be provided to open and close the air outlet at will.

Furthermore, the air outlets 6 and 7 may be formed of a porous plate material such as punched metal, or may be provided with fins that allow adjustment of the airflow direction.

Next, an opening 8 is bored in the bottom of the housing 2, and above the opening 8, grooves 10 for holding a pre-filter 9, which will be described below, are formed in both side plates, so that the filter 9 can be removed and replaced with a single touch. ing.

Since this prefilter 9 is close to the floor,
If a metal or resin mesh filter is used instead of a fibrous filter to inhale a mixture of various particles and not reduce the absorption capacity of the rotor blades described later, cleaning will be possible even when dirty. For example, it can be used repeatedly, reducing running costs.

Further, above the filter 9, a housing 2 is provided.
An electric motor 12 is attached to a bracket 11 fixed to a frame (or a frame, not shown), and its drive shaft 13 is disposed in the height direction of the housing 2, that is, in the vertical direction.

A rotor blade 14 is arranged at the upper end of this shaft 13,
A secondary filter 15 is arranged above it.

As an example, this filter 15 has a particle size of 0.3
It has the ability to attach and collect dust particles of ~300 microns.

That is, the filter 15 is made of glass fiber or the like, and the fibers are closely spaced, and the dust particles, insect bodies, or bacteria are attached to the fibers, and then sent to the tertiary filter 16 at the next stage.

The tertiary filter 16 is, for example, HEPA (High Efficiency Particulate) made of glass fiber.
Air) filter or ULPA (Ultra Low
A Particulate Penetration Air (Particulate Penetration Air) filter is installed to trap particles as small as 0.1 microns.

The filter 15 may be an antibacterial filter, that is, one in which a chemical is applied to the fibers, a deodorizing filter, that is, one in which activated carbon is applied to the fibers, or a charged filter, that is, one in which the fibers are charged with either a negative or a positive charge. , integrally laminated, a combination of any of the above, or a single layer glass fiber filter.

Furthermore, the bracket 11 is connected to an electric motor 12.
The drive shaft 13 of the motor 1 is arranged at intervals of 180 degrees, 120 degrees, or 90 degrees, and the electric motor 1 is attached to the bracket 11.
The second housing 12a is fixed.

On the other hand, on the front plate 4 of the cleaner 1, an operating switch 17 for the electric motor 12 and a pilot lamp 18 indicating the operating state are arranged above the switch 17.

Furthermore, the edge plate 19 at the corner of the bottom opening 8 has
Casters 20 are attached, one of which is provided with a stopper (not shown).

Therefore, in the air purifier of the present invention, when the operating switch is turned on, current is supplied to the electric motor, the rotor blades are rotated by the drive shaft, and a suction force that flows from the bottom to the top is generated. .

Then, insects such as mites parasitic or staying on the floor surface such as a carpet are forcibly sucked out from the suction port on the bottom.

The germs that are sucked up will stop breeding due to the antibacterial action of the filter.

At the same time, dust, mold bacteria, and other harmful bacteria circulating in the room are attached to the filter, and by the same antibacterial action as above,
Prevent breeding.

Furthermore, fine particles of 0.3 to 10 microns, such as cigarette smoke, adhere to and collect on the filter due to the charging effect.

In addition, it removes unpleasant odors such as cigarette smoke through its deodorizing effect.

As mentioned above, the air purifier of the present invention sequentially increases its cleanliness through the filters arranged in its housing, that is, the pre-filter in the lower stage, the secondary filter in the middle stage, and the tertiary filter in the upper stage. ing.

To replace or clean each of the above filters, remove the bottom row from below, and remove the middle and upper rows from below.
This is done by removing the upper housing.

Incidentally, it goes without saying that the casing of the present purifier may be provided with a sterilizing lamp or a storage chamber for a solid (or liquid) that generates a refreshing scent.

Although the above embodiment shows an example using a replaceable fibrous filter, for example, a filter that applies a high voltage to a needle-like substance to promote ion exchange in the air and charge and attach dust etc. may be combined.

[Effects of the invention] This invention is equipped with casters as described below to maintain a certain distance between the bottom of the purifier and the floor, and sucks indoor air, making it easy to move anywhere. Rather, the inlet port is closest to the carpet or tatami, and can forcibly inhale insects such as mites that are parasitic or lodged between the hair of the carpet or the tatami.

In addition, because multiple filters are arranged in a multi-stage system, the level of cleanliness can be dramatically increased. Coupled with the ability to move freely on the surface and inhale them, it is a highly practical idea that greatly improves usability.
