[Embodiment 1]
FIG. 1 is a front view of the lighting device with an air purifying function according to the first embodiment. FIG. 2 is a cross-sectional view taken along the line AA of FIG. FIG. 3 is a schematic cross-sectional view taken along the line BB of FIG. FIG. 4 is a perspective view of the lighting device with an air purifying function according to the first embodiment. Note that FIG. 4 is a perspective view of the state of being suspended from the ceiling as viewed from diagonally below.

The lighting device 101 with an air purifying function of the first embodiment shown in FIGS. 1 to 4 is a so-called hanging type lighting device.

The lighting device 101 with an air purifying function includes a housing 110, a first filter 120, a lighting 140, an exhaust unit 150, and a guide 300. The lighting device 101 with an air purifying function irradiates the illumination light downward in the drawing. Further, the lighting device 101 with an air purifying function takes in air from the side and the lower side of the housing 110, purifies the air by the first filter 120 inside, and exhausts the air upward.

The lighting device 101 with an air purifying function is installed at intervals from the ceiling while being suspended from the ceiling. Therefore, the upper part of the housing 110 is used by being hung from a hook ceiling body (not shown) of, for example, a hook ceiling rosette (so-called hook ceiling, hook rosette, etc.) mounted on the ceiling. For this purpose, the hook sealing cap 601 connected to the hook sealing body, the cord 602 connected to the electrode (not shown) in the hook sealing cap 601 and the mounting bracket (or another mounting bracket) of the hook sealing body (not shown). A wire 603 for hanging the wire 603 is provided. Since the wiring and electrodes are well known, the description thereof will be omitted. The lighting device 101 with an air purifying function receives power from the hook sealing body, but is not limited to this, and a cord for connecting to an outlet or the like may be provided separately. In FIG. 2, the hook sealing cap, the cord, and the wire above the housing 110 are not shown (the same applies to the other cross-sectional views).

(Case)
The housing 110 has a cylindrical shape and houses the first filter 120 inside. The housing 110 is larger than the housed first filter 120. The housing 110 is provided with a plurality of intake holes 112 on the entire circumference of the side (also simply referred to as “side surface” in the present specification) with respect to the hanging direction of the lighting device 101 with an air purifying function. The intake hole 112 is provided to suck in the air of the environment. The number and diameter of the intake holes 112 are appropriately designed depending on the rigidity and durability of the housing 110. For example, the intake hole 112 is formed so that the opening ratio is 30 to 70% in the range where the intake hole 112 is formed.

By providing the plurality of intake holes 112, the housing 110 also serves as a pre-filter and can capture relatively large dust and the like in the environment at the time of intake.

It is preferable that the plurality of intake holes 112 are provided at least in a range where they overlap with the outer surface (first surface) of the cylindrical first filter 120 in front view, rear view, and side view. By providing a plurality of intake holes 112 in such a range, air can be efficiently sucked from the outside of the first filter 120. The front view, the back view, and the side view are each viewpoint with the direction shown in FIG. 1 as the front.

Although the shape of the intake hole 112 shows an example of a circular punching hole in the figure, the shape is not limited to such a shape. For example, polygonal shape, stripe shape (hanging direction, orthogonal or diagonal intersection in the hanging direction (and stripes orthogonal or intersecting, etc.)), and other imitations of plants, animals, fantasies, etc. Any shape such as a character shape may be used as long as it allows air to pass through. Further, the entire housing 110 may be a wire mesh processed into a cylindrical shape.

The lower end of the housing 110 is extended so as to be below the lower end of the first filter 120. At the lower end of the housing 110, an eaves 160 having a ring shape and an opening (opening 115) at the center is provided from the housing 110. The eaves portion 160 is provided so as to be inclined upward (ceiling direction) in the direction of the opening from the connection portion with the housing 110. Further, along the shape of the eaves 160, substantially parallel to the eaves 160, it is inclined upward from the connection portion with the housing 110 toward the opening 115, and then gently downwards toward the center of the opening 115. A protruding lower surface portion 161 is formed. As a result, air flows smoothly from the opening 115.

Further, the eaves portion 160 and the lower surface portion 161 having such a shape can prevent the inside of the device from being seen by a person. This is because the lighting device 101 with an air purifying function is usually installed above the line of sight of a person. By arranging the eaves portion 160 and the lower surface portion 161 at such an angle, the inside of the device cannot be seen when a person looks up at the lighting device 101 with an air purifying function.

A gap g1 (see FIG. 3) is provided between the housing 110 and the outer surface (first surface) of the first filter 120. This gap g1 is spatially connected to the opening of the eaves 160. Therefore, the housing 110 is provided with an opening 115 below in the hanging direction. The lighting device 101 with an air purifying function sucks in the air below through the gap g1 and the opening 115.

(1st filter)
As described above, the first filter 120 is housed in the housing 110. There is a gap g1 between the first filter 120 and the housing 110. The interval of the gap g1 is not particularly limited as long as it is an interval through which air passes. For example, although it depends on the size of the entire device, if the diameter of the housing 110 (the direction orthogonal to the hanging direction) is 100 to 400 mm, the gap g1 is preferably about 1 to 50 mm. By setting the interval of such a gap g1, the air from the opening 115 provided below can be efficiently sucked.

The first filter 120 is formed in a cylindrical shape as a whole. The cylindrical first filter 120 purifies by sucking air from the outer surface (first surface) and passing it through the inner surface (second surface).

The inside of the cylindrical first filter 120 forms a flow path 124 (see FIG. 3) through which purified air passes. A lid portion 122 is provided on the lower portion of the first filter 120 of the cylinder to close the lower portion of the flow path 124. The lower portion of the flow path 124 is blocked by the lid portion 122 to prevent air from directly entering the inside of the first filter 120 from the outside.

The first filter 120 includes a dust collecting filter 125 and a deodorizing filter 126 (see FIG. 3). The dust collecting filter 125 is formed in a cylindrical shape and is arranged on the outer periphery of the deodorizing filter 126. As the dust collecting filter 125, a punching type in which a large number of holes are provided in metal or resin, a cut bend type, a mesh type such as a lath net, a non-woven fabric type, or the like can be adopted. In the present embodiment, the dust collecting filter 125 adopts a non-woven fabric type. The dust collecting filter 125 can collect finer dust and the like than the housing 110 that acts as a filter.

The deodorizing filter 126 has a built-in activated carbon or the like, and when the air passes through, it adsorbs the odor contained in the air and separates and removes the odor from the air. The deodorizing filter 126 may be coated with a deodorant to deodorize the attached odorous component.

The deodorizing filter 126 is a filter that is bent in a bellows shape and has a cylindrical shape as a whole. By forming the deodorizing filter 126 in a bellows shape, the surface area can be increased and the deodorizing efficiency can be improved. The deodorizing filter 126 has a cavity inside. This cavity serves as a flow path 124 through which the air purified by the dust collecting filter 125 and the deodorizing filter 126 passes. That is, the environmental air outside the housing 110 passes through the dust collecting filter 125 and the deodorizing filter 126 and flows into the flow path 124.

The first filter 120 is not limited to the dust collecting filter 125 and the deodorizing filter 126, and may include a smoke removing filter, a grease filter, and other filters.

(Cover)
The lid portion 122 is formed in a flat plate shape, for example. The lid portion 122 is connected to the eaves portion 160 connected to the housing 110 by a support column 123 (see FIG. 2). As a result, the lid portion 122 is fixed to the housing 110 with a gap g1. The support column 123 is formed so as not to obstruct the air flow passing through the gap g1. The first filter 120 is supported in the housing 110 by the lid portion 122.

(illumination)
The illumination 140 is attached to the lower surface of the lid portion 122. Therefore, the lighting 140 is provided below the housing 110, and irradiates the light downward of the lighting device 101 with an air purifying function.

For example, an LED lamp is used as the lighting 140. The LED lamp has a structure in which the surface of the LED chip (not shown) is covered with a cover (the cover constitutes a part of the lower surface portion 161). The illumination 140 has a structure in which the central portion protrudes from the lid portion 122. During the operation of the lighting device 101 with an air purifying function, the surface of the lighting 140 is exposed to the air flow passing through the opening 115, so that dirt is unlikely to adhere to it.

Instead of the LED lamp, an incandescent light bulb socket may be provided on the lid 122 so that a light bulb type LED lamp, a light bulb type fluorescent lamp, or an incandescent light bulb can be attached. When the incandescent light bulb socket is provided in the lid portion 122, the central portion of the lid portion 122 is recessed in the direction of the flow path 124, and the socket is provided in the recessed portion so that the amount of protrusion of each lamp is reduced. May be good.

(Exhaust part)
The exhaust unit 150 is located above the housing 110 and has a fan 152. The fan 152 is arranged above the first filter 120. Therefore, the fan 152 is located on the extension axis of the flow path 124.

The exhaust unit 150 is separated from the gap g1 portion on the outside of the first filter 120 in the housing 110 by a partition plate 155 so that air is not directly sucked from the outside of the first filter 120 by the operation of the fan 152. I have to.

The fan 152 generates an air flow that sucks in the environmental air outside the housing 110. That is, an air flow that passes through the intake hole 112, flows from the outer surface (first surface) of the first filter 120 to the inner surface (second surface), and passes through the flow path 124 is generated, and the opening 115 and the gap g1 are generated. To generate an air flow passing through the flow path 124 from the outer surface (first surface) to the inner surface (second surface) of the first filter 120.

The airflow guided to the flow path 124 is discharged from the exhaust port 154 formed on the upper surface of the exhaust portion 150. In the first embodiment, the exhaust port 154 is provided in the exhaust portion 150 so as to exhaust air in the top surface direction (upward direction) facing the ceiling. In terms of appearance, an intake hole 112 (punching hole) is also provided in a portion of the housing 110 where the exhaust portion 150 is located (see FIG. 1), but this portion has a closing plate 156 in close contact with the inside of the housing 110. It is provided so that the exhaust unit 150 is not directly exhausted in the lateral direction. The intake hole 112 in the portion of the housing 110 where the exhaust portion 150 is located is not necessary because it is for giving a sense of design unity with other portions.

(guide)
The guide 300 is attached to the outside of the housing 110 with a gap g2 via the spacer 301 (see FIG. 3). A constant gap g2 is maintained in the guide 300 over the entire outer circumference of the housing 110 by the spacer 301. The interval of the gap g2 is not particularly limited as long as it is an interval through which air passes. For example, although it depends on the size of the entire device, if the diameter of the guide 300 (the direction orthogonal to the hanging direction) is 110 to 500 mm, the gap g2 is preferably about 5 to 50 mm. By opening a gap g2 between the guide 300 and the housing 110 in this way, the guide 300 guides the air under the housing 110 toward the intake hole 112.

At least a part of the guide 300 is provided so as to have an ov (see FIG. 2) that overlaps the range in which the intake hole 112 of the housing 110 is opened. That is, it is preferable that the lower end of the guide 300 is the same as the lower end of the housing or below the lower end of the housing, and is the upper end of the guide 300 the same as the upper end of the range in which the intake hole 112 of the housing 110 is opened? Alternatively, it is preferably below the upper end. Here, the range in which the intake hole 112 is opened is the range in which the intake hole 112 through which the air actually taken in is actually passed. Therefore, the range where there is an intake hole 112 blocked by the closing plate 156, such as the intake hole 112 around the exhaust portion 150, is excluded.

Specifically, for example, the guide 300 is arranged so that the overlap ov in the hanging direction is 1 to 100% with respect to the range in which the intake hole 112 is opened. The more the overlap ov between the guide 300 and the range where the intake hole 112 is opened, the easier it is to suck the air below, and the less the overlap ov between the guide 300 and the range where the intake hole 112 is opened, the more. It becomes easier to breathe air from the side.

When the overlap ov between the guide 300 and the surface provided with the intake hole 112 is 100%, since there is a gap g2 between the guide 300 and the housing 110, not only air is sucked from under the gap g2 but also air is sucked. Since air is sucked from above the gap g2, the air of the entire space can be sucked. Further, the noise generated inside the housing 110 leaking from the intake hole 112 can be sound-insulated (or suppressed), and can also serve as a blindfold for the intake hole.

On the contrary, even if the overlap ov is about 1%, the suction airflow from the intake hole 112 can suck the air from below by the guide 300.

Such overlapping ov is preferably about 5 to 90%. By setting the degree of overlap in this way, it is possible to effectively purify the air in the entire space by achieving both suction from the side and suction from below. The overlapping ov is more preferably about 30 to 60%. By setting the degree of overlapping ov in this way, it is possible to suck in from the side and the bottom in a well-balanced manner. This overlapping ov is appropriately set depending on whether the air is to be sucked in more from the side or the lower side from the space.

The region where the intake hole 112 and the guide 300 overlap is a negative pressure region. Therefore, an ascending flow from the lower end of the guide 300 is generated in the gap g2 portion between the intake hole 112 and the guide 300. The generated ascending flow flows along the inner surface of the guide 300, and the flow is sucked into the intake hole 112. Due to this ascending flow, not only the air directly under the housing 110 but also the air around the bottom of the device can be sucked.

Although the guide 300 is fixed to the housing 110 in the first embodiment, the position of the guide 300 in the hanging direction can be moved within a range of 1 to 100% of the surface provided with the intake hole 112. You may. By making the guide 300 movable in this way, the suction ratio between the side and the lower side can be changed to a setting desired by the user.

Further, in the first embodiment, the guide 300 is provided parallel to the outer surface of the housing 110 at a substantially constant distance from the housing 110. However, the guide 300 is not limited to this, and may have a shape such that the upper part is narrow and the lower part is wide and the cross section in the vertical direction is trapezoidal. With such a shape, since the guide 300 spreads downward, air is sucked not only from the air directly under the lighting device 101 with an air purifying function but also from a wider range under the lighting device 101 with an air purifying function. You will be able to do it.

Further, the material of the guide 300 is not limited. For example, a metal plate is processed into a cylindrical shape. Further, for example, a transparent or translucent (including frosted glass) material may be processed into a cylindrical shape. As the transparent or translucent material, for example, glass or resin can be used. When a resin is used, it is preferable to use a flame-retardant resin depending on the installation location.

According to the first embodiment described above, the intake holes 112 are provided around the side surface of the housing 110, and the gap g1 is connected between the housing 110 and the first filter 120, and the gap g1 is connected below the housing 110. By providing the opening 115 and further providing the guide 300 with a gap g2 on the outer periphery of the housing 110, it is possible to suck in the air below and the air on the side of the lighting device 101 with an air purifying function. As a result, the air below the housing 110 is sucked in through the opening 115, and the air that cannot be completely sucked in through the opening 115 flows along the inner peripheral surface and / or the outer peripheral surface of the guide 300, and the air intake hole on the side of the housing 110 It is guided to the vicinity of 112 and is efficiently inhaled. Therefore, one lighting device 101 with an air purifying function can efficiently purify the air in the entire space.

A modification 1 of the first embodiment is a lighting device 101 with an air cleaning function provided with a second filter 220 at the bottom of the housing 110. Since other configurations are the same as those in the first embodiment, the description thereof will be omitted.

The second filter 220 serves as a pre-filter for air sucked through the gap g1 between the housing 110 and the first filter 120 and the opening 115. The second filter 220 is provided between the eaves portion 160 and the lid portion 122 so as not to block the light emitted downward from the illumination 140.

The second filter 220 may have a function of purifying relatively large dust or dust, and may be, for example, a metal mesh filter. Further, a non-woven fabric filter or the like for removing oily smoke or the like may be used.

By providing such a second filter 220, it is possible to prevent dust and dirt from entering the gap g1 between the housing 110 and the first filter 120, the eaves 160, and the like, and insects from entering. be able to.

The ring illumination 145 is a ring-shaped LED lamp in which a plurality of LED chips are attached under the eaves 160, which is the lower end of the housing 110, and a cover is attached thereto. Since other configurations are the same as those in the first embodiment, the description thereof will be omitted.

By providing the ring illumination 145 in this way, the design can be different from that of the first embodiment described above. In particular, it is possible to change the effect of light when the ring illumination 145 is turned on.

In the second modification, the ring illumination 145 is provided, and the central illumination 140 (see FIG. 4, hereinafter referred to as the central illumination) is not attached under the housing 110. However, a central illumination may be provided along with the ring illumination 145. By attaching both the ring illumination 145 and the central illumination, a different design can be obtained, and different light effects can be produced. Further, the ring illumination 145 and the central illumination may be individually turned on and off.

In the third modification, by providing the ring illumination 146 on the guide 300, the design is further different from that of the other embodiments and the second modification, and the light effect can be different.

(Other variations of lighting position)
The position of the illumination is not shown, but may be further provided at various positions. For example, it can be provided on the outer peripheral surface of the guide 300. The illumination provided on the guide 300 may be continuously illuminated in a ring shape, or may be illuminated so as to be scattered in the ring.

Further, the lighting can be provided in the gap g2 portion between the housing 110 and the guide 300 (however, the lighting is not obstructed by the air flow sucked from under the device). When it is provided in the gap g2 portion, not only the illumination light is emitted downward but also the illumination light is emitted upward, so that the light effect as indirect illumination can be obtained. Further, it may be provided on the upper part of the housing 110 to obtain a light effect as indirect lighting. Further, the lighting may be provided, for example, in the gap g1 between the housing 110 and the first filter 120. By providing the lighting 140 inside the housing 110 in this way, it is possible to allow light to leak to the outside from the intake hole 112 of the housing 110, and it is possible to produce an unusual effect of the light. Further, the illumination may be provided by combining these various positions, or the color of the illumination light may be changed.

[Embodiment 2]

FIG. 10 is a front view of the lighting device with an air purifying function according to the fourth embodiment.

The lighting device 104 with an air purifying function of the fourth embodiment shown in FIG. 10 is a hanging type lighting device as in the first embodiment.

The lighting device 104 with an air purifying function of the fourth embodiment has an upper guide 400 that guides airflow laterally and downward above the housing 110. Since it is the same as the first embodiment except that the upper guide 400 is attached, the description thereof will be omitted.

As described above, in the fourth embodiment, by providing the upper guide 400, the purified airflow exhausted above the housing 110 can be guided laterally and downwardly.

For example, from a dish placed on a countertop, water vapor components and odor components rise toward the ceiling. In particular, when cooking using a tabletop stove, oily smoke may rise.

By installing the lighting device 104 with an air purifying function on a table, it is possible to purify a large amount of water vapor components, odor components, oil smoke, and the like. However, some of the water vapor component, odor component, oil smoke, etc. may reach the ceiling directly.

The lighting device 104 with an air purifying function can blow off water vapor components, odor components, and oil smoke that directly reach the ceiling with purified air in the lateral or downward direction by the upper guide 400. A part of the water vapor component, the odor component, and the oily smoke that has been blown off is diffused, and a part is sucked from the intake hole 112 and purified in the process of returning downward or rising again.

As a result, the lighting device 104 with an air purifying function can suppress the water vapor component, the odor component, and a part of the oily smoke from reaching the ceiling and prevent the ceiling from becoming dirty.

Further, by installing a plurality of lighting devices 104 with an air purifying function according to the fourth embodiment, the air purifying effect is enhanced. For example, a plurality of lighting devices 104 with an air purifying function are installed within the range of the air flow blown out by the upper guide 400. In this way, the water vapor component, the odor component, the oily smoke, etc. blown off by the upper guide 400 are sucked by the lighting device 104 with an air purifying function within the range of each other's air flow.

In the fourth embodiment as well, the second filter 220 may be provided as in the first modification, or the illumination may be provided at various positions as in the second and third modifications. Further, even if the upper guide 400 is provided with respect to the second or third embodiment, the same effect as that of the fourth embodiment can be obtained. Of course, also in the fourth embodiment, as in the other embodiments, one lighting device 104 with an air purifying function can efficiently purify the air in the entire space.

[Embodiment 5]
FIG. 11 is a front view of the lighting device with an air purifying function according to the fifth embodiment.

The lighting device 105 with an air purifying function of the fifth embodiment shown in FIG. 11 is a hanging type lighting device as in the first embodiment.

In the lighting device 105 with an air purifying function of the fifth embodiment, a ceiling direction guide 500 is provided so as to surround the periphery of the housing around the position of the exhaust portion 150 of the housing 110. Further, an external partition plate 501 is provided outside the housing 110. Since the same is the same as in the first embodiment except that the ceiling direction guide 500 and the external partition plate 501 are attached, the description thereof will be omitted.

In the fifth embodiment, by providing the ceiling direction guide 500, the purified air exhausted upward from the exhaust unit 150 can be exhausted more strongly upward, that is, toward the ceiling. The airflow that has flowed to the ceiling further flows laterally and downwardly, and then flows below the lighting device 105 with an air purifying function (dashed line arrow in the figure).

Further, by attaching the external partition plate 501, it is possible to prevent the air reflected from the ceiling and flowing downward from being directly sucked into the intake hole 112 on the way, and to allow more air to be taken under the lighting device 105 with an air purifying function. Can be delivered to.

As described above, in the fifth embodiment, by creating an air flow from the ceiling direction to the downward direction, more air in the space where the lighting device 105 with an air purifying function is installed, particularly air from the ceiling to the side of the device is further increased. Since it can be purified, a wider range of air can be purified.

The external partition plate 501 may not be provided. Even if there is no external partition plate 501, air that reflects off the ceiling and flows downward is generated, so that a wide range of air can be purified.

Also in the fifth embodiment, the second filter 220 may be provided as in the first modification, or the illumination may be provided at various positions as in the second and third modifications. Further, even if the ceiling direction guide 500 and the external partition plate 501 are provided with respect to the second or third embodiment, the same effect as that of the fifth embodiment can be obtained. However, even in these cases, the external partition plate 501 may not be provided. Of course, also in the fifth embodiment, as in the other embodiments, one lighting device 105 with an air purifying function can efficiently purify the air in the entire space.

Although the embodiments and modifications to which the present invention is applied have been described above, the present invention is not limited to these embodiments and modifications. In each of the above-described embodiments, a cylindrical housing 110 and a cylindrical first filter 120 corresponding to the housing 110 are used. Instead, both the housing 110 and the first filter 120 may have a polygonal tubular shape such as a triangular cylinder, a square cylinder, a pentagonal cylinder, a hexagonal cylinder, a seven-sided cylinder, or an octagonal cylinder. The polygonal cylinder shape refers to a cylinder shape that becomes polygonal in a cross section along the line BB in FIG. For example, the housing 110 is a cylinder and the first filter 120 is a polygonal cylinder. In this case, since a gap with the housing 110 is created in the flat portion of the polygonal cylinder of the first filter 120, the top portion of the polygonal cylinder may be in contact with the housing 110. On the contrary, the housing 110 may be a polygonal cylinder, and the first filter 120 may be a cylinder. In this case, since a gap is created between the top portion of the housing 110 and the first filter 120, the flat portion of the housing 110 may come into contact with the first filter 120. Of course, in either case, the housing 110 and the first filter 120 may be completely separated from each other. Further, both the housing 110 and the first filter 120 may have a polygonal cylinder shape. When the housing 110 has a polygonal cylinder shape, it is preferable that the guide 300 also has the same shape.

Further, when the illumination 140 is provided in the center, a heat radiating portion of the illumination 140 may be provided inside the cylindrical first filter 120. As a result, the lighting 140 can be air-cooled, and high-power lighting can be easily installed. In this case, it is preferable that the fins of the heat radiating portion have a fixed blade shape and rectify. By doing so, it is possible to reduce the decrease in efficiency of the fan 152. Further, when the air cooling function is provided, for example, the specification may be such that the fan 152 is always driven when the illumination 140 is turned on, or the specification is such that the rotation speed of the fan 152 is changed according to the brightness.

Further, in each embodiment, the installation range of the intake hole 112 (the intake hole that actually has an intake action) overlaps with the outer surface (first surface) of the first filter 120 in the hanging direction. However, the present invention is not limited to this, and the intake hole 112 may not be provided in a part of the lower part of the housing 110. In each embodiment except the second embodiment, air is taken in from below the housing 110 through the opening 115 and the gap g1. By not providing the intake hole 112 in a part of the lower part of the housing 110 in this way, the airflow from below passing through the opening 115 and the gap g1 and the airflow from the side passing through the intake hole 112 do not directly collide with each other. Air from below that passes through the opening 115 and the gap g1 can be sucked in more efficiently.

In addition, the present invention can be modified in various ways based on the configurations described in the claims, and these are also within the scope of the present invention.
