Description

{INDOOR DEODORIZER WITH STERILIZATION FUNCTION}

The present invention relates to an indoor deodorizer having a sterilizing function.

Generally, air conditioners equipped in vehicles are divided into ventilation devices and cooling and heating devices. Here, the ventilation device is a device that changes the polluted air inside the vehicle to fresh air from the outside or circulates the air inside the vehicle (hereinafter, “inside”) and removes pollutants through a filter to keep the inside air comfortable.

The air conditioning system selectively maintains the temperature inside the vehicle in winter and summer by supplying the engine coolant and the air conditioner compressor refrigerant from the air conditioner to the heater core and evaporator of the air conditioning unit, respectively.

The air conditioner of such a vehicle is intended to create a more pleasant and comfortable interior environment for the driver and passengers by regulating and maintaining the interior temperature at a comfortable temperature. Generally, the air conditioner unit of a vehicle is composed of a blower that draws in outside air (hereinafter, “outside air”) or inside air, an evaporator that cools the drawn-in air with a refrigerant, and a heater core that heats the drawn-in air with the heat of a coolant. Each of these units is integrated into a single structure to form an air conditioner.

However, as the vehicle ages, the evaporator and heater core through which the air sucked in by the blower passes become covered with various foreign substances and dust, providing an environment in which various bacteria and mold can grow, causing the driver and passengers to breathe air contaminated with unpleasant odors and various bacteria.

In particular, in the summer when the temperature is high, various bacteria and molds multiply rapidly, which causes unpleasant odors and various bacteria cause respiratory diseases. To solve this problem, a cleaning solution has been sprayed on the intake side where the outside air and inside air are sucked in by the blower.

These existing solutions cannot cleanly wash away various foreign substances and dust stuck to the evaporator and heater core, cannot sterilize various bacteria and molds that are actively growing, and have the inconvenience of requiring users to pour in cleaning solution every day.

Meanwhile, Korean Patent Publication No. 10-2021-0066536 discloses a UV sterilization module installed inside an air channel that introduces air into the vehicle or provides purified air. However, in the case of such a UV sterilization module, it is not only difficult for the driver to install it directly, but also the driver must be aware of the location and specifications when installing it directly, which increases the burden on the driver in terms of time and cost.

The present invention is intended to solve the problems of the above-mentioned prior art, and its purpose is to provide an indoor deodorizer capable of effectively purifying air flowing into an indoor space such as the interior of a vehicle.

However, the technical tasks that this embodiment seeks to accomplish are not limited to the technical tasks described above, and other technical tasks may exist.

Hereinafter, with reference to the attached drawings, embodiments of the present invention will be described in detail so that those skilled in the art can easily practice the present invention. However, the present invention may be implemented in various different forms and is not limited to the embodiments described herein. In addition, in order to clearly describe the present invention in the drawings, parts that are not related to the description are omitted, and similar parts are assigned similar drawing reference numerals throughout the specification.

Throughout the specification, when a part is said to be "connected" to another part, this includes not only the case where it is "directly connected" but also the case where it is "electrically connected" with another element in between. Also, when a part is said to "include" a component, this does not mean that it excludes other components, but rather that it may include other components, unless otherwise stated.

Hereinafter, an embodiment of the present invention will be described in detail using the attached drawings.

First, an indoor deodorizer according to one embodiment of the present invention may be a device that is installed in any partially or fully closed indoor space to block and sterilize odors and harmful substances in the air stagnant or circulating in the space. A representative example is a device that is installed inside a vehicle to sterilize and deodorize air discharged through the vehicle's air vent, but the installation location does not limit the present invention.

FIG. 1 is a perspective view of an indoor deodorizer according to one embodiment of the present invention. As illustrated in FIG. 1, the front (F) and the back (B) of the indoor deodorizer are defined. Accordingly, the direction formed by the front (F) and the back (B) is a longitudinal direction, and the direction toward the front (F) is defined as the front, and the direction toward the back (B) is defined as the back. In addition, with respect to the indoor deodorizer and each component, the part close to the front (F) is defined as the front end or the top, and the part close to the back (B) is defined as the back end or the bottom.

Fig. 1(a) is a drawing showing an indoor deodorizer as seen from the front side, and Fig. 1(b) shows an indoor deodorizer as seen from the rear side. Referring to these, the indoor deodorizer can be designed to have a structure in which indoor air is drawn in from the back side (B), passes through an internal filter (30), and then radially discharges purified air near the front side (F).

Specifically, the frame (10) forming the exterior of the indoor deodorizer may have at least one opening (221) formed on the back surface (B) through which air may be introduced, and a filter (30) may be arranged in an internal region in contact with the back surface (B) and supported by the back surface (B) and the side surface. In Fig. 1, a back surface (B) in which a plurality of openings (221) having a comb-like shape are continuously formed is illustrated, but any opening that allows air to circulate smoothly and accommodates a filter (30) is sufficient, and the shape is not particularly limited.

The filter (30) can deodorize and purify the incoming air. For example, the filter (30) can physically filter out harmful substances such as dust, foreign substances, bacteria, mold, and microorganisms contained in the air discharged from the indoor air vent, and can be designed so that the air from which such harmful substances have been filtered is re-introduced into the indoor air. In addition, at least a portion of the surface of the filter (30) can be subjected to a microbial coating treatment to enhance the deodorizing ability.

The frame (10) includes a discharge portion (50) formed along the periphery, and the side of the frame (10) except for the discharge portion (50) is closed so that the air path passing through the filter (30) is formed vertically. As illustrated in FIG. 1, the frame (10) may form a discharge portion (50) through which the air inside is discharged to the outside as a part of the side between the filter (30) and the front (F) is horizontally cut off and opened, and the front (F) may be designed to be closed. Accordingly, the air purified through the filter (30) may be radiated in all directions through the discharge portion (50) rather than being ejected in a certain direction. At this time, as illustrated in FIG. 1, the frame (10) may be formed so that the cross-sectional area of the discharge portion (50) and its vicinity is larger so that the radiation speed and range of the purified air may be maximized.

Although not shown in FIG. 1, a cover part may be formed between the filter (30) and the discharge part (50) inside the frame (10). The cover part has a general plate shape and is spaced apart in front of the filter (30) inside the frame (10) so as to cover at least a portion of the flow path formed inside the frame (10). Preferably, the cover part may be arranged longitudinally parallel to the filter (30). That is, the cover part may be formed with a smaller area than the cross-section of the frame (10) so as not to completely block the flow of air. Accordingly, the cover part may act as a radial center of gravity, thereby contributing to the effect of allowing purified air to be widely distributed. Meanwhile, an input part (43) may be formed on the edge of the cover part, and since the input part (43) is exposed to the outside of the frame (10), a separate power supply module may be inserted.

Although not shown in FIG. 1, a sterilizing section may be formed inside the frame (10). As an example, the sterilizing section is a space formed between the filter (30) and the cover section when they are spaced apart from each other, and ultraviolet rays are supplied to air passing through the filter (30) to perform a sterilizing action. As a related example, the cover section may be a circuit board, and at least one UV light source may be mounted thereon to irradiate ultraviolet rays of a preset wavelength range toward the sterilizing section and the filter (30). In addition, at least one LED light source that irradiates visible light forward may be mounted on the cover section.

Hereinafter, the structure of an indoor deodorizer will be described in more detail using FIGS. 2 to 5. FIG. 2 is a cross-sectional view of an indoor deodorizer according to an embodiment of the present invention, FIG. 3 is an exploded view of the indoor deodorizer showing the internal structure based on the front (F), and FIG. 4 is an exploded view of the indoor deodorizer showing the internal structure based on the back (B).

According to one embodiment, the frame (10) may include a first frame (100) and a second frame (200). In addition, the second frame (200) may include a filter upper housing (210) and a filter lower housing (220). The filter upper housing (210) and the filter lower housing (220) are coupled to each other, and thus a space may be formed therein to accommodate a filter (30) and protect it from the outside. In addition, the filter upper housing (210) and the first frame (100) are coupled to each other, and thus a space may be formed in which a cover part (40) is arranged therein and includes the cover part (40).

That is, depending on the embodiment, the indoor deodorizer may be composed of a first frame (100), a cover part (40), an upper filter housing (210), a filter (30), and a lower filter housing (220). An indoor deodorizer is implemented by combining each component, and each component is also manufactured to be easily separated.

<Frame 1>

The first frame (100) is located at the top of the frame (10), forming the front (F) and covering the front, which is the direction in which the air inside travels straight.

According to one embodiment, the first frame (100) is spaced apart from the second frame (200) and is mutually coupled, and the gap formed thereby functions as a discharge portion (50). As illustrated, when the indoor deodorizer is implemented in a cylindrical shape, the gap may be formed along the circumferential direction between the first frame (100) and the second frame (200). Accordingly, as the air drawn in through the opening (221) passes through the filter (30) and is radiated around through the discharge portion (50), the purified air is spread in all directions.

According to one embodiment, the first frame (100) may have an input cover (103) formed near the edge. The input cover (103) is arranged in parallel with the input (43) of the cover (40) and the input support (213) formed in the upper filter housing (210) on the same line, and thus an insertion hole into which a power supply module is inserted is formed. At this time, the input cover (103) and the input support (213) are in close contact with each other, and an outlet (50) may be formed corresponding to the protruding length of the input cover (103).

According to one embodiment, the first frame (100) may be implemented as a plate shape whose cross-sectional area gradually increases toward the discharge portion (50). Accordingly, some of the air that has passed through the filter and reached the first frame (100) may move along the inner surface to the discharge portion (50), thereby maximizing the radiation effect.

According to one embodiment, the first frame (100) and the discharge portion (50) may have a larger cross-sectional area than the area of the frame (10) where the filter (30) is positioned. Accordingly, the radiation effect of the purified air passing through the filter may be maximized.

According to one embodiment, the first frame (100) may include at least one first hole (101) for fastening with the cover portion (40) and the second frame (200). The first hole (101) may be formed at the upper end of the first frame (100) and may extend rearwardly to a length that reaches the cover portion (40). Alternatively, the first hole (101) may extend rearwardly to a length that passes through the third hole (41) in the cover portion (40) and reaches the cover portion support portion (211) formed in the filter upper housing (210). Meanwhile, the first hole (101) may have screw threads formed along part or all of the extended length for fastening.

According to one embodiment, the first frame (100) may include a second hole (102) into which a protrusion (212) in the second frame (200) is inserted. As illustrated, the second hole (102) is formed on the opposite side of the input portion cover portion (103) to connect the first frame (100) to the filter upper housing (210).

According to one embodiment, a transparent portion (104) having a predetermined shape may be formed on the front surface of the frame (10). As illustrated, the transparent portion (104) is formed at the center of the first frame (100) and may be designed to have a transmittance that allows all or part of visible light generated inside to pass through, unlike other areas. Accordingly, a portion of the light output from the front surface of the cover portion (40) is exposed to the outside according to the shape of the transparent portion (104). This provides excellent aesthetics and can inform the user of the amount of power supplied to the cover portion (40) or the operating status according to the intensity or amount of light. Meanwhile, although the transparent portion (104) is illustrated as a ring shape in the drawing, the shape of the transparent portion (104) is not limited thereto. The front of the frame (10) is implemented in the form of a touch switch at least in part to selectively drive or stop the sterilizing light source (46) mounted on the cover portion (40), and the color of the light output from the front of the cover portion (40) can be changed depending on whether the sterilizing light source (46) is driven.

<Cover>

The cover part (40) is shaped like a plate and is arranged on the upper part of the second frame (200) to cover at least a portion of the path through which air passing through the filter (30) moves forward. Accordingly, a sterilizing part (60) that is completely closed but has only an area not covered by the cover part (40) open can be formed between the filter (30) and the cover part (40). Accordingly, air passing through the filter (30) stays in the sterilizing part (60) for a predetermined period of time and then moves to the discharge part (50), so that the sterilizing effect treated in the sterilizing part (60) can be increased.

According to one embodiment, the cover part may be formed of a circuit board having at least one light source mounted thereon. For example, the cover part may be formed of a PCB to control the operation of the light source mounted therein. Fig. 5 shows the arrangement of the cover part (40), and Figs. 5(a) and 5(b) show embodiments of the front and back surfaces of the cover part (40), respectively. Meanwhile, for the sake of explanation, only the main components of the cover part (40) are illustrated in the drawings, and various circuits and elements electrically connected to the light source are omitted as general components.

According to one embodiment, the cover part (40) may be placed on the upper part of the filter upper housing (210). For example, the cover part (40) may be secured to a cover part support part (211) formed on the filter upper housing (210) and supported from the rear by the cover part support part (211).

According to one embodiment, the cover part (40) may be formed with at least one third hole (41) for fastening with the frame (10). For example, the third hole (41) is positioned on the same line as the fourth hole formed in the cover part support part (211), and as a screw inserted into the fourth hole penetrates from the rear, the cover part (40) may be fastened with the cover part support part (211).

According to one embodiment, the cover part (40) may be mounted with at least one visible light source (45) on the front facing the discharge part (50). The light source (45) is preferably an LED having a predetermined color, but is not limited in type as long as it is a device that outputs visible light. Accordingly, light of a color set in the light source (45) may be emitted in all directions through the discharge part (50). In addition, as described above, light of the light source (45) may be output forward through the transmission part (104) of the first frame (100). Furthermore, the LED (45) may be mounted to emit light in a plurality of set colors, and may selectively show different colors depending on the operating state of the device, thereby helping the user to easily identify the operating state of the device with the naked eye.

According to one embodiment, the cover part (40) may be equipped with at least one ultraviolet light source (46) on the rear surface facing the filter (30). For example, the light source (46) may be a UV (Ultraviolet Ray) light source. Accordingly, ultraviolet light is irradiated toward the sterilizing part (60) and the filter (30) to maximize the sterilizing effect of air introduced into the filter (30).

According to one embodiment, the UV light source (46) can irradiate ultraviolet rays having at least a portion of a wavelength range of 100-400 nm. For example, the UV light source (46) can be designed to irradiate light of any one of a UV-C wavelength range of about 100-280 nm, a UV-B wavelength range of about 280-320 nm, and a UV-A wavelength range of about 320-400 nm. However, it is preferable to irradiate ultraviolet rays of the UV-C wavelength range having the highest sterilizing power, and most preferably, the wavelength range may be 260-280 nm. Meanwhile, when the UV light source (46) is designed for a UV-A wavelength range, the filter (30) may include a photocatalytic component that reacts with UV-A ultraviolet rays to cause anion sterilization. For example, the photocatalyst may be a TiO2 component, but is not necessarily limited thereto.

According to one embodiment, the cover part (40) as described above may include an input part (43) that can receive power from the outside. For example, the input part (43) may be placed in an insertion hole formed by the input part cover part (103) and the input part support part (213). The input part (43) is implemented as a USB port, and a power supply module suitable for the version of the port may be selectively connected, and accordingly, power may be supplied to the cover part (40) through an indoor power supply source.

According to one embodiment, a battery having a preset capacity for driving the cover portion (40) may be mounted inside the frame (10). The battery may be a primary or secondary battery, and a secondary battery is preferable because it can eliminate inconvenience due to replacement. If the battery is a secondary battery, charging and discharging is possible with power transmitted through the wiring of the input portion (43).

According to one embodiment, a second frame (200) is positioned at the rear end of the frame (10) to form a back surface (B), and provides a space in which a cover part (40) and a filter (30) are accommodated through a filter upper housing (210) and a filter lower housing (220).

<Filter upper housing>

The filter upper housing (210) provides an area in which a cover part (40) is installed at the front end and a space at the rear end that embraces the upper part of the filter (30). Fig. 5 illustrates an embodiment of the filter upper housing (210) with the cover part (40) arranged.

According to one embodiment, the cover portion (40) is formed smaller than the cross-section of the frame (10), so that it can shield only a part of the filter upper housing (210). Preferably, the cover portion (40) is positioned at the center of the cross-section of the frame (10) so that a ventilation path (P) can be formed along the inner circumference of the filter upper housing (210). Accordingly, most of the air passing through the filter (30) has a path that passes through the ventilation path (P) and along the inner surface of the frame (10) to the discharge portion (50), so that the purified air does not stay but naturally spreads indoors.

According to another embodiment, as shown in FIG. 6, the cover part (40) may include an opening (47) formed in at least a portion of the area for ventilation. At this time, the cover part (40) may be formed in the center of the cross-section of the frame (10), but the size of the cross-section may not be limited. For example, if more emphasis is placed on the sterilization effect, the cover part (40) may be formed so that its perimeter is in contact with the inner surface of the frame (10). Or, if more emphasis is placed on ventilation, the cover part (40) may be formed smaller than the cross-section of the frame (10). Meanwhile, at least one opening (47) may be formed. For example, as shown in FIG. 6(a), the cover part (40) may have a donut shape with a large hole (47) formed in the center, or as shown in FIG. 6(b), a plurality of openings (47) may be formed in one area in the form of porous holes to further secure ventilation.

According to one embodiment, the filter upper housing (210) may have at least one protrusion (212) formed at a position corresponding to the second hole (102) of the first frame (100) to be inserted into the second hole (102).

According to one embodiment, the filter upper housing (210) may have at least one cover part support (211) formed on the upper portion. At this time, the cover part support (211) may be formed to cover only one area, not the front surface of the cover part (40). For example, a plurality of cover part support parts (211) may be formed at regular intervals along the inner surface of the filter upper housing (210), and may extend to the center to an area that does not shield the UV light source (46). Accordingly, the cover part (40) has a structure in which it is stably fixed while not hindering the sterilization effect.

According to one embodiment, as described above, a fourth hole may be formed in the cover portion support member (211) for fastening with the cover portion (40) and the first frame (100). A screw thread may be formed in the fourth hole, and the screw thread may extend to the first hole (101). That is, the first hole (101), the third hole (41), and the fourth hole are positioned in parallel on the same line, and the first frame (100), the cover portion (40), and the second frame (200) may be firmly fastened by a screw inserted from the rear through the fourth hole. However, although the screw type is exemplified, it should be interpreted that any fastening method using a known technique, such as sliding or fitting using a step structure, is included in the scope of the present invention.

According to one embodiment, a side wall (215) may be formed around the cover portion (40). For example, the side wall (215) may be formed perpendicularly to the cover portion support portion (211) along the periphery of the cover portion (40) and may extend forward. At this time, referring to FIG. 2, it is preferable that the side wall (215) be formed to extend further forward compared to the position of the discharge portion (50). Accordingly, the flow of air near the center of the discharge portion (50) is blocked by the side wall (215), and the discharge portion (50) is implemented in a ring shape with only the outer periphery open.

Through this structure, air passing through the filter (30) moves directly to the exhaust port (50) along the inner side of the frame (10) and is radiated without staying or being lost inside, so that the speed and range of the purified air spreading inside the room can be maximized. In addition, a portion of the light irradiated from the light source can be blocked by the side wall (215) or the amount of light emitted to the outside can be controlled. That is, while minimizing the phenomenon of ultraviolet rays being exposed to the outside through the side wall (215), the amount of visible light emitted can be controlled to produce a soft visual effect.

According to one embodiment, the filter upper housing (210) protects the upper portion of the filter (30) placed in the filter lower housing (220) as the rear area of the cover portion support portion (211) is opened. At this time, a sterilizing portion (60) may be formed between the filter (30) and the cover portion (40) while combined with the filter lower housing (220), and air passing through the filter (30) in the space remains for a predetermined period of time and then moves to the discharge portion (50) along the inner surface via the ventilation passage (P). As a result, the time for which the introduced air is exposed to UV increases, so that the sterilizing effect can be maximized.

<filter>

The filter (30) implements the function of removing odors and harmful substances from indoor air introduced through the back surface (B) of the frame (10) and sterilizing it. Therefore, the filter (30) may be formed at the bottom of the frame (10), and is preferably positioned so as to be in contact with the back surface (B) to minimize the loss of air introduced through the opening (221).

According to one embodiment, the filter (30) may be formed so as to be arranged parallel to the cover part (40) as described above, but spaced a predetermined distance rearward from the cover part (40). Accordingly, a sterilizing part (60) is formed in the empty space between the cover part (40) and the filter (30), and air passing through the filter (30) is sterilized in the space and then moves along the inner surface of the frame (10) to the discharge part (50) and spreads in all directions.

According to one embodiment, the filter (30) may be protected from the outside by the combination of the filter upper housing (210) and the filter lower housing (220) after being placed or coupled to the filter lower housing (220). As described above, the upper portion of the filter (30) may have a structure in which the periphery thereof is covered by the filter upper housing (210), and the lower portion thereof by the filter lower housing (220).

According to one embodiment, the filter (30) may include at least one porous layer (32) in which a plurality of porous holes (H) are formed, and activated carbon grains (C) may be filled between each porous hole (H).

Preferably, as illustrated in FIG. 7, the filter (30) may include at least one corrugated-type filter medium (33) in which a wave pattern is repeated to form porous holes (H). Each hole (H) is filled with activated carbon (C) implemented as small grains, and as activated carbon (C) powder adheres to the surface of the corrugated filter medium (33), a porous layer (32) is formed in which fine deodorizing particles cover the cross-section of the filter (30). Accordingly, an excellent deodorizing effect is achieved and ultrafine particles in the incoming air are filtered out, while pressure loss is minimized to secure excellent breathability.

According to one embodiment, the filter (30) may include a positron-coated dust-proof net (31) mounted on both ends. As illustrated in FIG. 7, the filter (30) may be finished on the front and back with a positron-coated dust-proof net (31) when a porous layer (32) is formed inside. This dust-proof net (31) exhibits a fine dust collection function, and accordingly, only purified air is discharged to the outside while other fine harmful substances including activated carbon are filtered inside. Meanwhile, the positron-coated dust-proof net (31) may include a preset antibacterial component, and in this case, in addition to deodorization and sterilization, air with antibacterial added is spread indoors.

According to one embodiment, the filter (30) may be configured to include an inorganic filter and an organic filter. The inorganic filter can preemptively remove odors, volatile organic compounds (VOCs), etc. contained in the introduced air. The inorganic filter may be a film or panel made of porous inorganic particles capable of adsorbing odors, volatile organic compounds, etc., such as zeolite, charcoal, iron, silica, etc., a film or panel coated with a slurry containing such porous inorganic particles, and a fine mesh structure made of fibers containing such porous inorganic particles.

The organic filter is provided at the rear end based on the direction of air movement and can subsequently remove fine dust, ultrafine dust, bacteria, mold, microorganisms, and other fine harmful substances that are not filtered by the inorganic filter. The organic filter may include at least one nonwoven layer, and may be formed by laminating two or more nonwoven layers as needed. The organic filter may be manufactured by processing a composition including a polymer resin, and the composition may include a certain amount of an inorganic material as needed. The nonwoven layer may include polymer fibers formed of the composition and pores formed therebetween.

In one embodiment, the filter (30) is treated with a microbial coating on at least a portion of its surface to enhance the deodorizing effect. For example, the back surface of the filter (30) that is open to the outside may be accompanied by a microbial coating.

That is, the filter (30) not only physically filters out dust or harmful substances contained in the air, but can also sterilize the air introduced into the frame (10).

<Filter lower housing>

According to one embodiment, the filter lower housing (220) is located at the rear end of the second frame (200), and has one end open to allow the filter (30) to be coupled thereto, and the other end forming the back surface (B) of the frame (10) to support the filter (30). As described above, at least one opening (221) is formed at the other end to allow indoor air to flow in, and a fastening portion (225) to which a fixing unit for installing the frame (10) to an external air vent is fastened can be formed in a closed area (preferably the center).

According to one embodiment, the filter lower housing (220) may have a fitting projection (224) formed on the upper end of the outer surface for coupling with the filter upper housing (210). The fitting projection (224) may be engaged with a fitting groove (214) formed on the inner surface of the filter upper housing (210). That is, the filter upper housing (210) and the filter lower housing (220) may be coupled or separated from each other in a rotationally engaging manner. Therefore, it is easy to replace the filter (30) inside the frame (10) with only a simple grip force without separate equipment.

According to one embodiment, as shown, a portion of the outer surface of the filter lower housing (220) may be implemented as a stepped structure with a repeated protruding pattern. Such a protruding pattern may help the user's grip when replacing the filter (30) and may provide frictional force to ensure that the fragrance agent, which will be described later, is firmly attached without being easily separated.

Hereinafter, an embodiment of the function of an indoor deodorizer will be described using FIG. 8. FIG. 8 is a schematic cross-sectional diagram for explaining the function of an indoor deodorizer. In order to help understand the flow of air and light, elements for structural combination are replaced with the above, and only the main components are illustrated. Meanwhile, as illustrated in FIG. 8, the flow of air is distinguished by a solid line, the flow of visible light (LED) by a dotted line, and the flow of ultraviolet (UV) is distinguished by a dashed line.

First, the deodorizing and sterilizing effects of an indoor deodorizer according to the embodiment are explained through the flow of air and UV.

S1: Air discharged from the vehicle's air vent, etc., flows into the filter (30) through the back of the frame (10).

S2: The inflowing air passes through a filter (30) to remove odors, harmful substances, and ultrafine dust.

S3: UV is irradiated from a light source mounted on the back surface of the cover portion (40) toward the filter (30) and the sterilization portion (60). Accordingly, the sterilization effect by UV is further accompanied inside the filter (30). Meanwhile, although UV is designed to be directed toward the filter (30), there is a possibility that some of it may be emitted to the outside due to internal reflection or refraction. However, the present embodiment has a structure of a frame (10) with a front side covered and a side wall (215) to block the path of UV, thereby minimizing UV exposed to the outside.

S4: All or part of the air passing through the filter (30) remains in the sterilization section (60) formed between the cover section (40) and the filter (30) for a predetermined period of time. Accordingly, the time for which the air is exposed to UV increases, thereby maximizing the sterilization effect. In addition, as the reflection or refraction of the air further progresses in the space between the filter (30) and the cover section (40), the deodorizing effect can also be maximized.

S5: Air purified by passing through the filter (30) is radiated through the discharge portion (50). At this time, the upper portion of the frame (10) is formed in a dish shape whose cross-section gradually increases toward the discharge portion (50) to supplement the radiation effect. In addition, the cover portion (40) acts as a center point that partially blocks the path of the straight air, thereby increasing the flow rate radiated to the discharge portion (50). Furthermore, when a side wall (215) extending to the upper portion of the discharge portion (50) is provided, the loss of air that reaches the upper portion of the frame (10) or stays briefly in the discharge portion (50) is minimized, so that the purified air spreads more widely and quickly.

Next, the additional effect of the indoor deodorizer according to the embodiment is explained through the flow of visible light irradiated by the LED.

S1: When power is applied to the cover part (40), light is emitted forward from the LED mounted on the front of the cover part (40).

S2: A portion of the investigated light is exposed to the outside through the transparent portion (104) formed on the front of the frame (10). Accordingly, the color of the LED is expressed in the shape or form of the transparent portion (104), so that the user can be notified of the operation or power amount of the indoor deodorizer while providing a visual effect.

S3: The irradiated light is not output in a fixed direction, but is emitted in all directions to the outside through the emission portion (50). That is, the light reaching the top of the frame (10) is reflected or refracted and then emitted through the emission portion (50). At this time, the side wall (215) can be a radial center point. Specifically, since the side wall (215) extends further forward than the emission portion (50), the light does not directly escape to the emission portion (50), but some reaches the inner side of the frame (10) and is reflected or refracted, or some is refracted along the side wall (215) and then emitted. Accordingly, the color set to the LED is gently spread inside the room, thereby achieving excellent aesthetics. In particular, the amount of light exposed to the transmission portion (104) is greater than the amount of light emitted from the emission portion (50) during the same time period by the side wall (215), so that an effect can be produced in which the front is implemented in a relatively dark color and the surrounding area is implemented in a soft color.

Hereinafter, another embodiment of an indoor deodorizer will be described using FIGS. 9 and 10. FIG. 9 is a side view of an indoor deodorizer according to another embodiment of the present invention.

Fig. 9(a) illustrates a form in which a fragrance agent (70) is added to the indoor deodorizer of the aforementioned embodiment. As illustrated, the fragrance agent (70) is attached in a form that wraps around the outer surface of the frame (10) and emits a predetermined fragrance to the outside.

According to one embodiment, the scenting agent (70) may be attached in a form that surrounds one area of the filter upper housing (210) and one area of the filter lower housing (220). In this case, if the filter lower housing (220) has a shape with a repeated protruding pattern, the scenting agent (70) may be more firmly fixed.

According to one embodiment, the fragrance agent (70) may be formed in the form of an aroma band using, for example, an EVA (ethylene-vinyl acetate copolymer) material or a silicone material and may be implemented in a form that is embedded on the outer surface of the frame (10). Accordingly, it is possible to complement the disadvantages of existing fragrance agents that may cause dusting due to hardening and aging or become sticky when exposed to hot air from a vehicle's air vent for a long period of time.

According to another embodiment, the scenting agent (70) may be formed as a circular band (strip) containing scented scented granules. Here, the scented granules may be made of calcium material, and the band may be made of paper material.

More specifically, the fragrance agent (70) may be formed in a form including a frame in which PP material lattice shapes capable of fixing fragrance granules are continuously arranged, fragrance granules arranged between the frames, and a cover surface made of paper material that covers both the frame and the fragrance granules. In this way, since the fragrance agent (70) is implemented with a flexible material, it can be easily replaced with a new one even after long-term use.

Fig. 9(b) illustrates a form in which a fixing unit (90) is further added to the indoor deodorizer of the aforementioned embodiment. The fixing unit (90) is fastened to the back surface of the frame (10) and fixed to an external air vent, thereby inducing easy installation of the indoor deodorizer.

According to one embodiment, the fixing unit (90) may be fastened to a fastening member (225) formed around an opening (221) on the back surface of the frame (10). Preferably, the fixing unit (90) may be connected to the center of the back surface for dynamic stability.

According to one embodiment, the fixing unit (90) may be implemented as a fixing leg (90) in the form of a leg, as shown in FIG. 9(b). However, this is only an example showing a structure suitable for a vehicle air vent, and as shown in FIG. 10, the fixing unit (90) may have various embodiments.

For example, the fixing unit (90) may be implemented in the form of a clip as shown in Fig. 10(a), may be implemented in the form of a pair of tongs as shown in (b), and may be implemented in the form of a stand with four supporting legs as shown in (c). In addition, the fixing unit (90) may be installed in a variety of ways in addition to the form shown in Fig. 10, in the form in which it can be installed in the air vent.

The above description of the present invention is for illustrative purposes, and those skilled in the art will understand that the present invention can be easily modified into other specific forms without changing the technical idea or essential characteristics of the present invention. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive. For example, each component described as a single component may be implemented in a distributed manner, and likewise, components described as distributed may be implemented in a combined form.

The scope of the present invention is indicated by the claims described below rather than the detailed description above, and all changes or modifications derived from the meaning and scope of the claims and their equivalent concepts should be interpreted as being included in the scope of the present invention.
