Accordingly, a flow of air is separated into the ceiling side and the floor side by the shade 3, the air can be convected forcibly by a fan of the part of an air cleaner installed in the central part of the shade 3, in consequence, in the vicinity of the central part of a circular fluorescent lamp 13 and thus almost the whole smoke flows along the forced convection by the fan in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention integrates a ceiling-mounted lighting device and an air purifier and can be used as a lighting device. Alternatively, the odor can be removed.

[0002]

2. Description of the Related Art Most of conventional small-scale air purifiers are of a stationary type and have a single function as an air purifier. However, the basic function of purifying air is not sufficiently effective. In addition, because it is a stationary type, a place for installation is required, and placing it near a wall or an object is restricted. In addition, the cost of materials other than the basic mechanism was too large. The conventional technology and its problems are described.

FIG. 18 shows an example of a conventional small-scale air purifier, in which negative ions are generated by corona discharge of a sharp negative electrode 79, and dust and dirt, as well as dead mites, are collected in close contact with the positive electrode 80. Collect on dust paper 81. Air flows in and out of the lower hole 77 and the upper hole 78 opened in the panel 76 due to ion wind generated when negative ions are drawn to the positive electrode.

[0004] However, since the ionic wind that causes convection of air is not large and is often placed in a low place in a room, air convection hardly occurs and dust cannot be collected efficiently. In addition, placing walls and furniture close to each other will also collect dust, which necessitates separate installation, which limits the choice of place. Also, since it handles high voltages, placing it underneath is not perfect for ensuring safety.

The conventional example shown in FIG. 19 has the same principle as that of the example shown in FIG. 18, and is of a stationary type. Negative ions are emitted by the sharp negative electrode 82, and dust is collected on a dust collecting paper 84 in close contact with the positive electrode 83. Air enters and exits through the slit holes 85 and 86.
However, the disadvantages are the same as in the example of FIG.

FIG. 20 shows another example of a conventional small-scale air purifier. The fan 94 forcibly sucks air from the slit hole 89 of the panel 87 and the circular slit 93
Then, air is discharged from the opening 96 by the flow straightening plate 95 of the case 88. Pre-filter 9 at the position where air passes
0, large area, fine-grained main filter 91
And an activated carbon filter 92 is further installed. Fan 9
4, air convection is forcibly generated. However, since it is a stationary type, there are problems such as restrictions on a place where the air convection can be effectively utilized, a drawback that the air convection in the entire room cannot be effectively utilized, and an excessive cost for an air purifying function. there were.

As another example, although not shown, there is an air purifier mounted on a wall. In the case of an air purifier that generates corona discharge, the disadvantage is the same as that of the stationary type.However, in the case of an air purifier in which air is forced to pass through a filter by a fan, air circulation is more effective than that of the stationary type, but indoors The air recirculation is not fully utilized, which makes installation difficult, and the overall cost is high for the function as an air purifier.

[0008]

The conventional small-scale air purifier has a common disadvantage that the air convection in the room cannot be effectively used, the dust collection efficiency is insufficient, and the air purifier is of a stationary type. The installation location is limited. In addition, the cost of a panel, a cord, and the like is required for the function as an air purifier, and the price is high.

According to the present invention, the dust collecting efficiency is increased by installing the apparatus in an optimum place indoors to cause efficient air convection. At the same time, the installation location is not restricted. In addition, the cost required for appearance can be hardly increased, and as a result, the price is low for the function, and it is possible to make the use of the air purifier uncomfortable.

[0010]

In order to achieve the above-mentioned object, in the air purifier with the ceiling hanging lighting device of the present invention, the air purifier is located at the center of the room where air convection is most likely to occur. And hang from the ceiling to install at height.

In addition, the air purifier alone is not suspended and is integrated into the lighting device. Therefore, the lighting device can be installed at an optimal place in a room without competing with the lighting device, and what is necessary for appearance and function is diverted from the lighting device for cost reduction.

The part of the air purifier, both in terms of design and function, is consequently integrated in the central part of the lighting device. The shade of the lighting device separates air convection between the ceiling and floor.

[0013] A ceiling air intake hole is provided in the case of the air purifier at the center of the lighting device. An opening through which air flows out is provided on the floor side of the shade.

In order to cause forced convection of air, a motor driven fan is provided on the air outflow side. Alternatively, ion wind is generated by acceleration of ions by high voltage without using a fan.

The large dust is a coarse pre-filter, the fine dust is a fine main filter, and an activated carbon filter for adsorbing odors and toxic gases is installed in the order of air inflow as required.

In order to make the above filters easily replaceable, the drawer which can be taken in and out of the case of the air purifier and has a lattice-shaped bottom for easy air permeation is independently provided for the pre-filter and the main filter. Provide or unite.

The negative electrode for causing corona discharge is sharpened, electrically insulated, and arranged at a distance from the positive electrode. Each electrode has air-permeable holes formed in a grid pattern. Alternatively, the electrodes may be housed in drawers that can be taken in and out.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on examples with reference to the drawings.

FIG. 1 is a partially cutaway perspective view of an embodiment of the present invention, and FIG. 2 is a sectional view thereof. A plurality of holes 2 are formed on the ceiling side of the case 1, and a shade 3 of a lighting device that continuously separates the ceiling side and the floor side by air convection in the case 1 is provided. The entire body including the case 1 and the shade 3 is supported by the hanging cord 4 and the stopper 12.

The appearance of the lighting device is almost the same as that of the conventional lighting device, and the weight does not increase so much that the hanging cord 4 cannot bear the weight. Typically, as shown in FIG.
Can be turned on by pulling. Shade 3
Is used to make the illumination on the floor side uniform and improve the brightness without unnecessary illumination on the ceiling side.

With respect to the purifying of air, which is the object of the present invention, air is forcibly sucked by a fan 5 from a hole 2 opened on the ceiling side of the case 1, collected by a straightening plate 6, and shaded under the case 1. Spills down. In the case 1 on the way, a pre-filter 9 and a fine main filter 10 are installed. Large dust is removed by the pre-filter 9, and fine dust is removed by the main filter. If necessary, an activated carbon filter 11 is provided for the purpose of deodorizing and adsorbing toxic gas.

The pre-filter 9 and the main filter 10
Are placed in the drawers 7 and 8 which are perforated by the bottom grid 16 and are held down by the holding grid 15 to be stabilized. If necessary, place the activated carbon filter 11 at the position closest to the air outlet,
Place in drawer 8. Further, the drawers 7 and 8 are provided with a handle 18 to facilitate handling.

An illumination light of a ceiling hanging illumination device is usually
It is installed at a high position in the middle of the room, slightly away from the ceiling. This location is best suited for forcing convection of room air. Forced convection can be effectively performed because shade 3 separates the air flow between the ceiling and floor,
This is because the air purifier is installed near the center of the shade 3 and consequently in the vicinity of the center of the annular fluorescent lamp 13 so that the air can be forcedly convected by the fan.

In fact, when examining the flow of air in a smoke test, the smoke rises from a source near the floor to the ceiling, disperses near the ceiling, and diffuses slowly throughout the room. Small dust also behaves almost in the same way. In particular, at a position such as an air purifier with a ceiling hanging lighting device of the present invention, the air convection is vertically separated by the shade 3 and the air near the ceiling is forcibly sucked by the fan 5 and flows down. Most of the flow follows the forced convection of the fan in a short time. The object of the present invention can be effectively achieved.

The efficiency of air convection and the manner of convection flow make it possible to make the room temperature uniform during cooling and heating and energy efficiency. If the convection is stagnant, high-temperature air accumulates near the ceiling during heating, and a temperature difference of 10 degrees or more from the vicinity of the floor easily occurs. A temperature difference also occurs during cooling. The downward wind flow of the fan that causes convection is ineffective at about 1 m, and the wind noise and rotation noise of the fan can be very low.

The air purifier with the ceiling hanging lighting device of the present invention can be installed at an optimum position in the middle of a room without any restrictions on the installation location of furniture and the behavior of people. It is especially effective in small and enclosed places such as condominiums and apartments.

In addition, what is used in the lighting device, such as the shade 3, which is necessary for appearance can be used, and the hanging cord 4 including the power cord can be used as it is. Therefore, the present invention can be embodied by adding only what is necessary as an air purifier, and cost can be reduced.
Also, the use of the air purifier does not give a feeling of strangeness.

FIG. 3 shows the dust collecting portion used in the embodiment of FIG. 1 separated into layers. The pre-filter 9 and the fine main filter 10 are stored in drawers 7 and 8 having openings at the bottom by lattices 16 and 20. By using the drawers 7 and 8 and attaching the handles 18 and 21, the filter can be easily taken in and out of the case 1 in FIG. Draw out the activated carbon filter 11 if necessary 8
It may be installed at the bottom of the. Pressing grids 15, 19 are used to stabilize each filter.

FIG. 4 is a sectional view of a plurality of filters combined into one drawer 24. The pre-filter 26 is accommodated from the air inflow side, the fine main filter 27 is arranged on the air outflow side, and the activated carbon filter 28 is optionally accommodated in the drawer 24 having a hole at the bottom lattice 30. The holding grid 29 stabilizes each filter. A handle 25 is attached to the drawer 24 to facilitate putting in and out.
By using a single drawer 24, the entire case 22 can be made smaller. Air is forcibly sucked from the plurality of holes 23 by the fan 5.

FIG. 5 shows the dust collecting portion combined into one of FIG. 4 with each layer separated. The drawer 24 has a greater depth than when two drawers are used. However, as already mentioned, the case 22 is thinner and structurally simpler.

FIG. 5 shows the use of the fine main filter 27 for collecting fine dust, and FIG. 6 shows the use of the main filter 31 having a large bent area. If a fine main filter is used, the pressure loss at the time of air permeation increases,
It is necessary to bend to reduce the resistance.

If the fine main filter 27 shown in FIG. 5 is not so large as to have a large pressure loss, there is a limit for collecting minute dust. If the main filter 27 is a filter of an aggregate of fibers charged with static electricity, the dust collection efficiency is greatly improved to a minute level. As a specific filter, it is appropriate to use an aggregate of electret fibers having a surface charged with polarized thin thin fibers.

The activated carbon filters 11 and 28 shown in FIGS. 3, 5 and 6 contain carbonized porous substances in a mesh or the like, and have a function of adsorbing odors and toxic molecules when passing through the air. Although the amount of generation is not necessarily large, it has been reported that negative ions are generated when passing through the air.

FIGS. 7 and 8 show another embodiment of the present invention in which the structure and principle of the dust collecting portion are different from each other, with a partially cutaway perspective view and a sectional view. The dust is charged by corona discharge to collect dust. However, it is divided into a ceiling side and a floor side by a shade 3, air is forcibly sucked by a fan 5 from a plurality of holes 2 of a case 1, a flow is gathered by a flow straightening plate 6, and an annular fluorescent lamp 1 is formed.
3. Drain from the center of 3. Similarly, the whole is supported by the hanging cord 4 from the ceiling.

A relatively large dust is removed by a pre-filter 32, and a sharp negative electrode 33 to which a high negative voltage is applied.
Generates a negative charge, and charges minute dust negatively. Positive electrode 3 with a hole to which a positive high voltage is applied
Place a fine main filter 35 near 6
Collects negatively charged dust reliably. The pre-filter 32 and the negative electrode 33 are housed in a drawer 38, and the main filter 35 and the positive electrode 36 are housed in a drawer 39.

Some negative ions not neutralized by the positive electrode 36 are diffused into the room by the fan 5. It has been pointed out that negative ions are better for health than positive ions. In fact, there are many negative ions in the forest and near the fountain, and there are many positive ions when the heater is burned, when using TV or electric appliances, or where there is a lot of exhaust gas. Therefore, generating negative ions is
In winter, heat with a gas or oil stove in a closed room,
This is necessary for the lives of modern people who use electrical appliances nearby. Therefore, the embodiment of the present invention in which dust is collected by corona discharge is also effective for health.

FIG. 9 shows the filter and the dust collecting portion of the electrode of the embodiment of FIGS. 7 and 8 separated from each other. Each filter is stabilized by holding grids 34,37. As shown in FIG. 10, the electrode plate 41 projects the protruding electrode terminal 42 to the outside in alignment with the groove 44 of the drawer 43. The electrode terminal 42 is located on the opposite side of the handle 45,
When the drawer 43 is stored in the case 1, the drawer 43 is brought into contact with a high voltage terminal formed inside the case 1.

FIG. 11 shows an embodiment of the present invention which collects dust by corona discharge. The difference from the embodiment of FIG. 7 is that the dust collecting unit is combined into one drawer 48. Case 4
6, the height is reduced and the structure is simplified. The same is true of forcibly sucking air from the hole 47 by the fan 5 and blowing the air downward from the center of the annular fluorescent lamp. 12, the negative electrode 33 is electrically separated from the positive electrode 36 as shown in FIG.
Through 0. The holding grid 51 is used for stabilizing the pre-filter 32 and the main filter 35. The holding grid 51 may be attached to the drawer 48 with a hinge structure,
You may make it the structure to fit.

FIG. 13 is a partially cut-away perspective view showing another example of the embodiment of the present invention which collects dust by corona discharge.
In the case of collecting dust by corona discharge in FIGS. 7 and 11, the air is forcibly convected by the fan 5, but the convection can be controlled in one direction without using the fan 5. In the case of FIG. 13 as well, a negative charge is generated by corona discharge from the sharp negative electrode 33 applied to a negative high voltage. Negative charge is a positive electrode with high positive potential 3
Suctioned at 6 and accelerated. At this time, the entire air becomes ionic wind, and as a result, the air is sucked from the plurality of holes 2, passes through the pre-filter 32 and the main filter 35 stored in the cases 38 and 39, and flows out of the protector 52. . However, it is weaker than the convection flow at the fan.

The sharp negative electrode 33 shown in FIGS. 7, 11 and 13 is used.
Even if the polarities of the positive electrode 36 and the negative electrode 36 are reversed, generation of charges by corona discharge and ion wind from the sharp electrode to the opposite electrode are possible in principle. However, corona discharge from a sharp electrode is more stable in the case of minus high potential. It is well known that negative ions generated and diffused into a room are healthier and more comfortable to the human body.

FIG. 15 shows another embodiment of the present invention. The dust collecting portion is an example of a configuration in which the dust collecting portion has a negative electrode 33 and a positive electrode 36 and collects dust by corona discharge. However, this embodiment includes a case where the dust collecting portion has a configuration in which the dust collecting portion is not a corona discharge. The air that has entered through the hole 2 on the ceiling side by the fan 64 rotated by the motor 62 is collected by the flow straightening plates 61 and 63, flows through the space between the original shade 3 and the added shade 65, and flows out in the floor direction. . The outflow wind is soft because it has a wide exit. The idea that the dust collection unit is installed near the center of the lighting device is consistent with the present invention. A lighting circuit for illumination is provided in the container 66.

FIG. 16 shows another embodiment of the present invention. The dust collecting portion causes corona discharge at the negative electrode 33 to generate ionic wind between the dust collecting portion and the positive electrode 36. The air is sucked from the plurality of holes 2 on the ceiling side, flows into the space between the original shade 3 and the added shade 67, and flows out toward the floor. By not using a fan, it is valuable to be free from the noise of the fan, even if it is quiet. Lighting circuit is container 6
Stored in 8.

FIG. 14 shows an internal frame structure for supporting and reinforcing the cases 1, 22, and 46 and the shade 3 used in each embodiment of the present invention. The cord 4 is hung by the stopper 12 at the center apex, and the cord 4 is fixed. A space is formed by the beams 53, the support pillars 54 and the rims 55, the strength of the space is maintained, and an entrance end 56 and an entrance bottom 57 for taking out the drawer, and a slide edge 58 and a slide bottom 59 are provided. The rim 55 supports the shade 3. Further, a high voltage terminal may be provided at the end plate 60. Cases 1, 22 and 46 are divided into beams 5
It is also possible to cover the 3 and the pillar 54 to make it easy to disassemble, assemble, and clean.

FIG. 17 shows another embodiment of the present invention. An air purifier having a dust collection unit housed in a case 72 is installed at the center of three lighting lamps 71 suspended by a suspension cord 69 and supported by a metal column 70. Air is sucked in from the upper hole 74, dust is collected by the dust collecting portion provided in the drawer 73, and the air flows out from the lower opening 75. The configuration of the dust collecting section may or may not use corona discharge. Although the use of a fan improves the dust collection efficiency, the use of a fan is not always necessary in the case of the corona discharge dust collection unit.

[0045]

Since the present invention is configured as described above, it has the following effects.

Since it can also be used as a lighting device, it can be installed at a position near the ceiling in the center of the room. As a result, the air purifier can be hung at a location optimal for convection of air, and the efficiency of collecting indoor dust is high, and dust can be collected evenly.

Since the shade of the lighting device separates the air on the ceiling side and the air on the floor side, forced convection of air by a fan or ion wind can be effectively performed.

Since the apparatus is hung on the ceiling, it is not necessary to install the apparatus on a place such as the floor where a person moves, so that setting of the place is not troublesome.

Since the shades and hanging cords necessary for the appearance can be diverted from those of the lighting device, it is only necessary to add a functional part as an air purifier, and the cost can be reduced for the entire function. Become.

Also, the appearance is the lighting device itself,
