[0002]

2. Description of the Related Art In the drawings, the same reference numerals are used for components having the same function and the like in order to avoid repetition of the description. The front and right sides are expressed as rear.

(Explanational drawings of conventional air purifiers (A) to (D)) As shown in FIGS. 1 to 4, the conventional air purifier includes a housing 7 supported on a floor 8 with feet 6. A fan 1, a purifying filter unit 2, a suction port 3, and an air outlet 4 are provided, and dirty air in the room is sucked from the air inlet 3 by the fan 1, and returned from the air outlet 4 through the purifying filter unit 2, thereby purifying the air. Had been done.

The purifying filter unit 2 uses a substance having a dust collecting effect, a substance having a deodorizing effect, or the like. For example, there is one that collects dust by attaching pollen, and one that deodorizes tobacco odor, body odor, pet odor, and the like. Structurally, a breathable film filter with fibrous or cottony irregularities is known.It is detachably attached and can be cleaned or replaced with water if it gets dirty, or carbon or deodorant. There is a filter that can be easily replaced with a filter included, and an electronic filter using a discharge electrode called an ozone type or an ion type.
In addition, a grill provided in the outlet 4 and the inlet 3 and rectifying the flow direction of the air and at the same time determining the wind direction is referred to as a grill 5 here.

[0005] The air purifier (A) shown in Fig. 1 is a device that sucks air from behind and discharges clean air to the front. FIG.
Is an air purifier (B) that sucks air from the front and discharges clean air upward. The air purifier (C) in FIG.
Is a thing that sucks air from behind and exhales clean air forward. The air purifier (D) shown in FIG. 4 is a device that sucks air from the surroundings and discharges clean air upward.

[0007] Accordingly, it has been noted that it has an effect of removing dust, pollen, odor of pets, and odor of cigarettes that enter the room through windows and float in the air.

[0008]

SUMMARY OF THE INVENTION The present invention provides a means for observing the cause of the generation of dirty air in a room with new eyes, discovering the problem, and removing the problem. Has solved. Therefore, the problem will be described first. (Explanation of light dust accumulation tendency) Fig. 5 shows pollen and futon dust (→) on pet hair (b) and clothes.
B) tend to accumulate in the room.

At first, the pet's hair falls around the pet, but when the pet or human walks around the room, the wind rises and soars temporarily, but when the pet or person leaves, the wind weakens and falls on the floor 8 from the air. After that, the hair is carried by the weak wind and the floor surface 8
There is a tendency to move and gather as if crawling. Therefore, hair tends to accumulate in the corner 13 of the room as shown by the dotted line in the figure. (In the case of long hair, a plurality of hairs are entangled, making it easier to move as if they were standing up like a sail like a figure.)

The pollen on the clothes falls at the place where the clothes are changed or the place where the clothes are hung with hangers or the like, but as shown in FIG.
Will be accumulated. The dust on the futon also tends to accumulate in the corner 13 of the room when the futon is raised and lowered, causing a wind.

Light dust 1 accumulated in the corners 13 of these rooms
In the second, when a pet or a person approaches the vicinity, a wind is generated and soars and drifts in the air, and when the person or the pet moves away, it starts to accumulate in the corner of the room again. Thus corner 13 in the room
, Light dust 12 accumulates, which pollutes the indoor air.
Was one of the causes.

Therefore, a situation in which a conventional air purifier is installed on the floor 8 at the corner 13 of the room to remove dirt and smell of the air due to the accumulated light dust 12 will be described below. (Explanation of the flow of air in the suction port) As shown in FIG. 6, the lower side 20 below the conventional suction port 3 is located sufficiently higher than the floor surface 8 (the height S above the floor surface is large). Even if the shape of the duct inside the mouth 3 is inclined downward as shown in the figure, since the suction port 3 is connected to the floor of the room at a discontinuous step, only air in a range higher than the floor 8 flows in. I can't do things. Further, the air near the floor 8 hardly flows into the suction port 3 due to the swirling flow 9 as shown in the figure. Therefore, the accumulated light dust 12 cannot approach the suction port 3 due to the swirl 9.

As described above, the conventional air purifier cannot remove the dirt and smell of air due to the light dust (pet hair, pollen, clothes and futon dust) accumulated in the room.
(Furthermore, among the particles having an odor, there was a tendency that putrefaction and the like progressed due to accumulation, and the odor became strong). This accumulation of light dust 12 is a particularly serious problem for those who keep dogs and cats with long hair indoors (especially when children are present). And allergies. Also, people who have been sleeping on the floor 8 for a long time due to illness or aging have been required to clean the air from the accumulated dust.

[0014]

The gist of the present invention will be described with reference to the accompanying drawings.

[0018]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Fourteenth embodiment of the present invention (how to implement the invention) which is considered to be the best embodiment will be described with reference to FIG. Will be described.

The air purifier of the present invention has a fan 1 as shown in the drawing.
And a purifying filter unit 2, a suction port 3, and an air outlet 4 are provided in the housing 7, and the suction port 4 is provided at a position for discharging air in a direction other than rearward and downward (obliquely upward in the front in the figure) Further, the lower side 20 on the lower side of the suction port 3 is made substantially the same height as the floor surface 8 on which the air purifier is installed, and is configured at a position where air is sucked from directions other than the downward direction and the rearward direction (frontward in the figure). Further, the lower side 20 on the lower side of the suction port 3 is formed at substantially the same height as the floor 8 on which the air purifier is installed.

In the above-described air purifier, a dust collecting filter 10 for collecting accumulated dust is configured to be detachable from the housing 7 in an air passage inside the suction port 3.

Further, the suction port 3 is constituted by a cartridge 18 which is movable in the vertical direction so that the lower side 20 of the suction port 3 becomes substantially the same height as the floor surface 8 and is detachably provided on the housing 7.

The air purifier constructed as described above is installed in the corner 1 of the room.
When the cartridge 1 is installed at the edge of the wall 28, the cartridge 1
Since the front end of the lower end 8 is positioned so as to be lower, the lower side 20 of the front inlet 3 is substantially the same height as the floor surface 8. Therefore, the light dust 12 which has accumulated in the room without the swirling flow 9 is taken into the air purifier from the suction port 3 without receiving any resistance.

Inside the suction port 3, a dust collecting filter 10 is provided by a wire mesh filter 14 made of a wire mesh with a large mesh and a coarse filter 15 made of a coarse or cottony or fibrous film. Therefore, the captured light dust 12 is collected by the two filters (14, 15) according to the size.

For example, the hair of a pet is a wire mesh filter 14,
Large pollen and large dust are captured by the coarse filter 15. Dust, pollen, and odor particles of a size smaller than that are collected and odor-eliminated by the same purifying filter unit 2 as in the related art. The clean air is discharged from the outlet 4 by the fan 1 into the indoor space in front of the floor 8 at a position higher than the floor 8.

When the air purifier of the present invention is installed on the floor 8 at the corner 13 of the room as shown in FIG. 20, the air on the floor 8 is taken into the air purifier from the suction port 3 and purified. It is released as clean air into the air at a high position.
This air circulation is always performed.

Since the air circulates along the floor 8 in this manner, the light dust 12 accumulated on the floor 8 is also taken into the air purifier. Accordingly, the light dust 12 accumulated in the air circulation gradually decreases over time, and thus dust and smell in the air in the entire room can be reduced. Thus, the present invention solves the conventional problems by a simple method.

[0027]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific embodiments of the present invention will be described with reference to the drawings.

First, the configuration, operation and effect of the shape of the lower side 20 of the suction port 3 according to the first and second aspects will be described. The drawings are (explanatory drawing of the first embodiment), FIG. 7, (explanatory drawing of the second embodiment), FIG. 8, and (explanatory drawing of the third embodiment) FIG. (FIGS. 7, 8, and 9 are shown in a perspective partial view and a sectional partial view for easy understanding.)

The shape of the suction port 3 of the first embodiment shown in FIG.
A bottom plate 29 is provided in the housing 7 and a dust collecting filter 10 composed of a wire mesh filter 14 having a coarse mesh is provided further forward. A dust collecting filter 10 for collecting large lightweight dust 12 such as pet hair is provided on the housing 7 in a detachable manner to enable washing and washing with water. Therefore, the height S of the lower side 20 of the air inlet 3 from the floor surface is slightly higher due to the detachable mounting frame of the dust collecting filter 10 (the wire mesh filter 14) and the bottom plate 29.

However, in the first embodiment, in order to make the height of the lower side 20 of the lower point of the lower end of the suction port 3 substantially equal to the height of the floor surface 8, parts such as the frame and the bottom plate 29 of the housing are used. To reduce the height of the composite. That is, the height S from the floor is 1
By setting the distance to 0 mm or less, the disturbance due to the vortex 9 (FIG. 6) is reduced, and the inflow of air from the floor 8 is facilitated.

The suction port 3 of the second embodiment shown in FIG. 8 has the same structure as that of the first embodiment, except that the bottom plate 29 of the housing 7 is not provided and the dust collecting filter 10 is formed on the base 24. Therefore, this dust filter 10 is mounted in the space below the housing 7 and the suction port 3
Is composed.

Further, the dust collecting filter 10 is provided with a wire mesh filter 14 having a large wire mesh on the front face and a coarse filter 15 of a coarse or cottony or fibrous film. The two filters (14 and 15) collect the light dust 12 taken in according to the size. For example, the hair of a pet is configured to be captured by a wire mesh filter 14, and large pollen and large dust are captured by a coarse filter 15.

Next, the lower side 20 of the lower pointed end of the suction port 3 is provided with an inclined surface 16 at the front so that the height of the lower side 20 is the same as the floor 8. The front of the base 24 is in contact with the floor 8 and the height of the rear is adjusted so that the tip of the inclined surface 18 always contacts the floor 8 or the tip of the inclined surface 16 is pressed by a spring or the like. Or an inclined surface made of an elastic member so as to always contact the floor surface 8. In the second embodiment, an inclined surface 16 made of rubber having a triangular cross section is provided at the front of the base 24 as shown in the figure, and the lower side 20 is at the same height as the floor 8.

With this configuration, the height S of the floor 8 and the lower side 20 of the suction port 3 from the floor surface can be made zero, and the lower side 20 of the suction port 3 is connected to the floor 8 continuously. Will be connected. Therefore, the vortex 9 (FIG. 6) is not generated, so that the air on the floor surface 8 can flow in straightforwardly. Therefore, the light dust 12 accumulated on the floor 8 can be easily sucked into the suction port 3.

In the second embodiment shown in FIG. 8, the tip of the base 24 is the inclined surface 16, but when the inclined surface 16 is provided when there is the bottom plate 29 as in the first embodiment, the height from the floor surface is increased. Height S can be reduced to zero. That is, an inclined surface 16 is provided at the front point of the bottom plate of the housing 7 and the front point of the dust filter 10, and the position of the lower side 20 of the suction port 3 combined as described above is set at the height of the floor 8. They may be matched.

In the third embodiment shown in FIG. 9, the bottom plate 29 of the housing 7 is not provided, and the suction port 3 is constituted by both side plates of the housing 7, the ceiling 30, and the installed floor surface 8. Therefore, as shown in the figure, a dust filter 1
Reference numeral 0 is attached to the ceiling side of the suction port 3 by the base 24 so as to be detachable and inclined. Further, since there is no bottom plate at the back of the suction port 3, a control plate 25 for changing the direction of the flow of air upward from the floor 8 is provided, and the lower end thereof is configured to contact the floor.

The dust filter 10 is provided with a comb filter 22 in which pins are arranged in a comb shape at the front, and a coarse filter 15 of a coarse cotton or fiber film is provided at the back. The length of the lower side of both filters 22 and 15 is set to the length up to the floor 8 as shown in the figure. Further, as shown, a plurality of holes (or grooves) into which the pins of the comb filter 22 enter.
May be inserted into the pins of the comb filter 22 and provided.

Since the suction port 3 is configured as described above, the air on the floor 8 can flow straight into the suction port 3 because there is no cause for generating the swirl 9 (FIG. 6). Therefore, the light dust 12 accumulated on the floor 8 is easily sucked into the suction port 3 and collected by the comb filter 22 and the coarse filter 15 according to the size. (Further fine dust, pollen and odor are left to the purification filter 2 inside the air purifier.) Since the base 24 is easily removable from the housing 7, for example, when pet hair is entangled with the filter. It can be removed and cleaned with the cleaning plate 22 or water.

Thus, as shown in the first to third embodiments, the lower side 20 of the suction port 3 of the present invention is almost the same height as the floor 8 (S <10 mm or S = 0). As an air passage, the suction port 3 is connected to the floor surface 8 continuously, so that the influence of the swirl 9 (FIG. 6) is reduced, and the light dust 12 accumulated on the floor surface flows into the suction port 3. Easy to do.

In the air purifier of the fourteenth embodiment, a fan 1, a purifying filter unit 2, an inlet 3 and an outlet 4 are provided in a housing 7, and the outlet 4 is provided at a front upper position and the outlet 4 The grill 5 is provided so as to guide the air flow obliquely upward in a plurality of directions on the left and right sides, and a dust filter 10 is further provided. And a cartridge 18 provided on the housing 7 so as to be detachable and attachable.
Is composed.

That is, the cartridge 18 containing the dust collecting filter 10 is inserted and attached to the housing 7 installed on the floor 8 with the feet 6. The cartridge is attached to a fulcrum 17 provided on the housing 7 by a locking portion 27 at the rear of the cartridge 18. The front part is fixed to the floor surface 8 by its own weight as shown in the figure. The through hole behind the ceiling 30 of the cartridge 18 is airtightly connected to the through hole on the lower side of the housing 7 by an elastic seal 26 (for example, rubber) provided on the periphery as shown in the drawing. Therefore, the air flowing into the inside from below the housing 7 passes through the inside of the cartridge 18 and proceeds to the purification filter unit 2 as shown by an arrow.

With such a configuration, the wall 2 at the corner 13 of the room
When installed on the floor 8 with eight floors, the air purified by the purification filter unit 2 is sent out by the fan 1 through the outlet 4 in a plurality of upper front directions. Thereafter, the air circulates through the floor 8 to the suction port 3. Further, since the lower side 20 in front of the cartridge 18 is lowered to the floor surface 8, the light dust 12 accumulated on the floor surface 8 without being affected by the swirl 9 (FIG. 6) is first sucked into the suction port 3 together with air. Cartridge 18
Is collected by the dust collecting filter 10.

As described above, since the air is circulated from above the room to the floor surface 8, the whole room air is cleaned with time. Further, since the cartridge 18 is configured to be detachable, it can be easily taken out and washed with water. In addition, since the position of the lower side 20 of the suction port 3 is determined on the floor surface 8 by its own weight, it is not necessary to adjust the height at the time of mounting.

As described above in the first to twentieth embodiments, the air purifier of the present invention can remove the dirt and smell of the air due to the accumulated light dust 12 by adding a simple configuration to the conventional air purifier. An excellent air purifier completely eliminated can be provided.

[0071]

According to the conventional air purifier, dust, pollen and odor drifting at a relatively high position in the room can be eliminated, but light dust 12 accumulated in the corner 13 of the room drifts again in the room. Air dirt could not be purified forever.

However, by installing the air purifier according to claims 1 to 3 in the corner 13 of the room, as described in the first to twentieth embodiments, a wide range from the air in the room at a high position to the floor 8 can be obtained. The air can be circulated even to this point, so that the light dust 12 accumulated in the puddle such as the corner 13 of the room can be easily collected to clean the entire air in the room.

Since the dirt and smell of the air in the room due to the air in a wide range, especially the light dust 12 accumulated on the floor surface, can be purified, pollen and dust on the futon which adhere to clothes and are brought into the room. It is possible to eliminate dirt and smell of air due to the light dust 12 accumulated.

Conventional air purifiers have been used especially for elderly and sick persons who have been bedridden on the floor 8 of a living room for a long period of time, or for families with infants who cannot stand still. Although respiratory and allergic disorders due to the influence of the dust 12 could not be reduced, the present invention is an optimal air purifier for those persons because the accumulated light dust 12 is collected.

When the person who keeps the pet indoors installs the air purifier of the present invention, not only the smell is reduced, but also the long hair loss or short hair loss (light weight) accumulated in the corner 13 of the room of the puddle. Dust 12) is also collected, and respiratory and allergic disorders due to hair loss can be prevented.

The air purifier of the present invention disregards the conventional configuration, shape and existing concept of air purifying action in a room, and conceives a purifying action by air circulation to the floor 8 which has been neglected until now. For this reason, by providing a new structure that makes the lower side 20 of the important suction port 3 almost the same height as the floor surface (S <10 mm or S = 0), an excellent air purifier can be provided simply as described above. it can.
