Description

  The present invention relates to an air purifier, and more particularly to an air purifier that can improve air suction efficiency while ensuring the design of a front portion.

  As a conventional air cleaner, a technique described in Patent Document 1 is known. In general, in an air cleaner, in order to efficiently suck in air, it is preferable that a suction port having a large opening area be formed in the front portion (front side) of the housing.

  However, since the air purifier is installed in a room that is noticeable by the user, there is a problem that its design restrictions are severe. For example, if the air inlet is too large, the structure inside the housing is visible from the outside, which is not preferable.

JP 2003-38925 A

  Therefore, the present invention has been made in view of the above, and an object thereof is to provide an air purifier capable of improving the air suction efficiency while ensuring the design of the front portion.

  In order to achieve the above object, an air purifier according to the present invention is an air purifier that purifies or deodorizes indoor air, and has an air suction port and a discharge port, and the suction port and the discharge port. A housing having a connecting air passage, a filter disposed on the air passage, and a blower for circulating air in the air passage, and having a plurality of curved surfaces having different curvatures. A surface shape of the body on the suction port side is configured, and a plurality of openings serving as the suction ports are respectively formed on the plurality of curved surfaces.

  In this air purifier, compared to a configuration in which an air inlet (opening) is formed in a flat or single curved housing, the area of the portion where the inlet (opening) can be formed (of the front panel) Surface area) increases. Therefore, since the suction port having a sufficient opening area can be formed, there is an advantage that air suction efficiency is improved. Moreover, since the freedom degree of arrangement | positioning of an opening part increases with the increase in the surface area of a housing | casing, there exists an advantage which can ensure the design property of a front part.

  In the air cleaner according to the present invention, the housing includes a front panel on the suction port side, and the front panel includes a base portion and a front decoration portion having a surface shape having a substantially arc cross section. A curved surface is comprised by the said base part and a front decoration part, and the said front decoration part has a bigger curvature than the said base part, and is arrange | positioned in the approximate center of the said base part.

  In this air purifier, the base part and the front decoration part have a surface shape (round shape) with a substantially arc cross section, so that air can be sucked into the housing not only from the front direction of the front panel but also from the oblique direction. Accordingly, there is an advantage that the air suction efficiency is further improved as compared with the configuration in which the front panel has a flat shape.

  In the air cleaner according to the present invention, the plurality of the openings are located farther from the inlet surface of the filter as being located closer to the center with respect to the inlet surface of the filter.

  In this air purifier, since the opening is located farther from the downstream filter (pre-filter, dust collection filter) toward the center of the front panel, the air passing through the center opening and the end side Air that has passed through the opening is sucked in substantially uniformly from the inlet surface of the dust collection filter. Thereby, there exists an advantage by which the process of the air by a filter is performed efficiently.

  In the air cleaner according to the present invention, the ratio of the opening area of the suction port to the surface area of the front panel is large at the center of the front panel and small at the end.

  In this air purifier, since a large amount of air is sucked from the center of the front panel, there is an advantage that the air sucking efficiency is improved.

  In the air cleaner according to the present invention, the longitudinal direction of the front panel and the central axis of curvature of the plurality of curved surfaces are substantially parallel.

  In this air cleaner, the front panel has a surface shape that spreads in the circumferential direction with the longitudinal direction as an axis. Thereby, since the air suction area is secured, there is an advantage that the air suction efficiency is improved.

  An air purifier according to the present invention is an air purifier that cleans or deodorizes indoor air, and includes a light source and a light guide unit that guides light from the light source, and a display surface by driving the light source. The display unit displays the operating state by turning on or off the light, and the peripheral surface of the light guide unit that is visible from the outside through the display surface is textured. .

  In this air purifier, when the display unit is turned on, light from the light source passes through the light guide unit and is emitted from the display surface to the outside. Thereby, the display surface appears to be lit and the operating state of the air cleaner can be visually recognized from the outside. Here, since the peripheral surface of the light guide portion is subjected to the texture processing, the light from the light source is diffused in the textured portion. Thereby, since light is diffusely reflected effectively in the light guide portion, there is an advantage that the visibility of the display portion is improved.

  In the air cleaner according to the present invention, the casing has a front panel, the suction opening is formed in the front panel, a vertical rib is disposed on the back side of the front panel, and the front panel. Is arranged on the upstream side of the filter with the back side facing the filter side, and a gap is provided between the vertical rib and the vertical beam of the filter.

  In this air purifier, the air sucked from the suction port (opening of the base portion) can flow to the downstream filter through the gap between the vertical rail and the vertical rib. Therefore, there is an advantage that the air suction efficiency is improved as compared with the configuration in which the vertical bars and the vertical ribs are in contact with each other or close to each other so that the air flow is inhibited.

  In the air cleaner according to the present invention, the casing has a front panel, the suction opening is formed in the front panel, a vertical rib is disposed on the back side of the front panel, and the front panel. Is disposed on the upstream side of the filter with the back side facing the filter side, and the extending direction of the vertical ribs and the pleat direction of the filter are substantially orthogonal to each other.

  In this air purifier, in a configuration in which vertical ribs are provided on the back surface of the base part, the air drawn from the opening of the base part straddles the vertical ribs (for example, a dust collecting filter). ). For this reason, it is preferable that the pleat direction of a filter follows the air flow direction across a vertical rib. Therefore, in the above configuration, the air straddling the vertical ribs flows smoothly along the pleat direction of the filter, so that there is an advantage that the air suction efficiency is improved.

  In addition, the air cleaner according to the present invention includes a light receiving unit that is disposed in the housing and receives an operation signal from the outside, and the light receiving unit provided in the housing and the light receiving window An external operation signal can be received through the suction port.

  In this air purifier, the light receiving unit can receive operation signals from both the light receiving window and the air inlet, so the light receiving unit can receive more light than the configuration in which the operation signal is received only from the light receiving window. There are advantages to being. In addition, such a configuration has an advantage that the degree of freedom in design is high compared to a configuration in which the light receiving range is enlarged by a large light receiving window.

  An air purifier according to the present invention is an air purifier for purifying or deodorizing indoor air, and has an air suction port and a discharge port and an air passage connecting the suction port and the discharge port. And a filter disposed on the air passage, and a blower for circulating air in the air passage, and the housing has a front panel and is lateral to the back side of the front panel. Ribs are arranged, the front panel is arranged on the upstream side of the filter with the back side facing the filter side, and the horizontal ribs press the vertical bars of the filter in the installed state of the front panel. It is fixed.

  In this air cleaner, since the vertical beam of the filter (for example, pre-filter) is fixed by the pressing of the horizontal rib, the curved deformation of the vertical beam is reduced. Thereby, there exists an advantage by which the position shift of a dust collection filter is prevented. For example, in a state where the vertical beam is deformed, there is a risk that large dust may pass through the gap of the deformed portion during operation to the subsequent filter (dust collection filter or the like) side. That is, the preceding filter (prefilter) does not function effectively. Then, it is necessary to clean the dust adhering to the subsequent filter, and the filter replacement cycle may be shortened. The above configuration is particularly useful when the vertical rail has a thin and easy-to-curve structure.

  In the air cleaner according to the present invention, the area of the portion where the suction port (opening) can be formed (compared to a configuration in which the air suction port (opening) is formed in a flat or single curved housing ( The surface area of the front panel is increased. Therefore, since the suction port having a sufficient opening area can be formed, there is an advantage that air suction efficiency is improved. Moreover, since the freedom degree of arrangement | positioning of an opening part increases with the increase in the surface area of a housing | casing, there exists an advantage which can ensure the design property of a front part.

  Hereinafter, the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments. The constituent elements of this embodiment include those that can be easily replaced by those skilled in the art or those that are substantially the same. In addition, a plurality of modifications described in this embodiment can be arbitrarily combined within a range obvious to those skilled in the art.

[Air cleaner]
The air purifier 1 is a device that is installed indoors to purify or deodorize air. In this embodiment, a deodorizer will be described as an example of the air cleaner 1.

  The air cleaner (deodorizer) 1 has a function of being installed indoors to reduce odors in the room and to reduce discomfort due to odors. The air purifier 1 is installed, for example, in living spaces of general households or elderly facilities, toilets, filth rooms, corridors, hospital waiting rooms or hospital rooms, clinic treatment rooms, pet hotels, animal hospital waiting rooms or treatment rooms, etc. The The air purifier 1 is installed, for example, on a floor surface in the room or attached to a wall surface in the room.

  The air cleaner 1 includes a housing 2, an adsorption deodorization unit (adsorption unit) 3, an ozone deodorization unit (ozone decomposition unit) 4, a blower 5, and a control unit 6 (see FIGS. 1 and 2). .

  The housing 2 is made of a box-shaped resin member. The housing 2 has a suction port 21 on its side and a discharge port 22 on its top. In addition, an air passage R extending from the suction port 21 to the discharge port 22 is formed inside the housing 2. And the adsorption deodorizing part 3, the ozone deodorizing part 4, and the air blower 5 are arrange | positioned on this air path R. FIG.

  The adsorption deodorizing unit 3 has a function of adsorbing dust and gaseous odor in the air. The adsorption / deodorization unit 3 is disposed on the air passage R in the housing 2 and in the vicinity of the suction port 21 of the housing 2. The adsorption deodorization unit 3 is, for example, a dust collection filter 31 that collects coarse dust or smoke odor (fine particles) in the air, a catalyst filter 32 that adsorbs and decomposes a gaseous odor in the air, and a catalyst filter 32. The activated carbon filter 33 temporarily accumulates the decomposition residue of the gaseous odor in the air that has passed through, and has a three-layer structure in which these are laminated (see FIG. 2). In addition, a pre-filter 30 that collects coarse dust is disposed in front of the dust collection filter 31.

  The ozone deodorizing unit 4 has a function of decomposing odors in the air with ozone. The ozone deodorizing unit 4 is disposed on the air passage R in the housing 2 and downstream of the adsorption deodorizing unit 3 (near the discharge port 22 of the housing 2).

  The blower 5 has a function of circulating air through the air passage R by blowing air. The blower 5 is configured by, for example, a sirocco fan, and is disposed on the downstream side of the adsorption deodorizing unit 3 and the upstream side of the ozone deodorizing unit 4.

  The control unit 6 performs drive control for the ozone deodorization unit 4 (ultraviolet lamp 42), drive control for the blower 5, and other control necessary for driving the deodorizer 1.

  In the air cleaner 1, when the blower 5 is driven during operation, indoor air is sucked from the suction port 21 and passes through the adsorption deodorization unit 3 (see FIG. 2). Then, the deodorizing process of the high-concentration odor is performed in the adsorption deodorizing unit 3, and strong odor in the air is removed. Specifically, first, coarse dust or smoke odor in the air is collected by the pre-filter 30 and the dust collection filter 31 of the adsorption / deodorization unit 3. Next, the gaseous odor in the air is adsorbed and decomposed by the catalyst filter 32. Next, the activated carbon filter 33 temporarily accumulates the decomposition residue of the gaseous odor in the air that has passed through the catalyst filter 32.

  Next, air is sent to the ozone deodorization part 4 through the air blower 5 (refer FIG. 2). In the ozone deodorizing unit 4, a deodorizing process for low-concentration odors in the air is performed, and minute odors in the air that have not been removed by the adsorption deodorizing unit 3 are removed. Specifically, in the case 41 of the ozone deodorizing unit 4, the ozone generated by the ozone generating unit (ultraviolet lamp) 42 reacts with air, and the air is deodorized. And the air which passed the ozone deodorizing part 4 is discharge | released indoors from the discharge port 22 of the housing | casing 2, and is reduce | restored. Thereby, indoor air is deodorized and a comfortable air environment is provided.

[Front panel]
In this air purifier 1, the housing 2 has a front panel 23 that covers the upstream side of the adsorption / deodorization unit 3 (see FIGS. 1, 3, and 4). A plurality of openings 211 are formed in the front panel 23, and the air inlet 21 is configured by these openings 211.

  Further, the surface shape of the front panel 23 on the suction port 21 side is constituted by a plurality of curved surfaces 231 and 232 having different curvatures. The curved surfaces 231 and 232 are respectively formed with a plurality of openings 211 that serve as the air suction ports 21.

  Specifically, the surface shape of the front panel 23 of the housing 2 is configured by a base portion 231 and a front decoration portion 232 having different curvatures. A plurality of openings 211 are formed in the base part 231 and the front decoration part 232, respectively, and the air inlet 21 is configured by these openings 211. Moreover, the base part 231 and the front decoration part 232 have the surface shape of the substantially circular arc cross section which has a mutually different curvature. In addition, the front decoration part 232 is fitted and arranged at the approximate center of the base part 231. For this reason, the front panel 23 is configured by a curved surface whose center (front decoration part 232) and periphery (base part 231) are different, and has a bilaterally symmetrical surface shape with the front decoration part 232 as the center.

  In such a configuration, the area (front panel 23) of the portion where the suction port 21 (opening 211) can be formed, as compared with a configuration in which the air suction port (opening) is formed in a flat or single curved housing. Surface area). Therefore, since the suction port 21 having a sufficient opening area can be formed, there is an advantage that air suction efficiency is improved. Moreover, since the freedom degree of arrangement | positioning of the opening part 211 increases by the increase in the surface area of the housing | casing 2, there exists an advantage which can ensure the design property of a front part.

  Further, in such a configuration, since the base portion 231 and the front decoration portion 232 have a surface shape (round shape) having a substantially arc cross section, air is sucked into the housing 2 not only from the front direction of the front panel 23 but also from an oblique direction. be able to. Accordingly, there is an advantage that the air suction efficiency is further improved as compared with the configuration in which the front panel has a flat shape. For example, in this air cleaner 1, the opening part 211 used as the air inlet 21 is formed so that it may reach from the center side of the base part 231 to an edge part (edge part of the front panel 23) (refer FIG. 3). . For this reason, since air is sucked into the housing 2 also from the end portion side of the base portion 231, the air suction efficiency is improved. Further, in the configuration in which the central portion (front decoration portion 232) of the front panel 23 has a larger curvature than the surroundings (base portion 231), the housing 2 is visually compared to the configuration having a uniform curvature as a whole. Has the advantage of looking smaller.

  In the air cleaner 1, the plurality of openings 211 are located on the center side with respect to the inlet surface (upstream surface) of the downstream filter (pre-filter 30 or dust collection filter 31, the same applies hereinafter). It is preferable that the position is farther from the entrance face of the filters 30 and 31 (see FIG. 4). In other words, the opening 211 of the front panel 23 located on the center side with respect to the entrance surface of the filters 30 and 31 is closer to the entrance surface of the filters 30 and 31 than the opening 211 of the front panel 23 located on the end side. It is preferable that it exists in a distant position. For example, it is preferable that the opening 211 of the front decoration 232 is located farther from the entrance surfaces of the filters 30 and 31 than the opening 211 of the base 231. Specifically, a structure in which the front decoration part 232 protrudes from the surrounding base part 231 to the front side of the housing 2 is employed (see FIGS. 3 and 4). For this reason, the front panel 23 has a substantially dome shape in which the central portion is swollen.

  In such a configuration, since the opening 211 is located farther from the entrance surface of the filters 30 and 31 toward the center of the front panel 23, the air that has passed through the opening 211 on the central side and the opening 211 on the end side pass. The sucked air is sucked from the inlet surfaces of the filters 30 and 31 substantially uniformly. Thereby, there exists an advantage by which the process of the air in the adsorption | suction deodorizing part 3 (filter 30, 31) is performed efficiently. For example, in the configuration in which the center side and the end side of the front panel 23 are at the same distance with respect to the planes of the filters 30 and 31, air is more likely to be sucked toward the center side. Is not supplied and is not preferable.

  Moreover, in this air cleaner 1, it is preferable that the ratio of the opening area of the suction inlet 21 with respect to the surface area of the front panel 23 is large in the center part of the front panel 23, and small in an edge part (refer FIG. 3). In such a configuration, since a large amount of air is sucked from the center portion of the front panel 23, there is an advantage that the air suction efficiency is improved.

  For example, in the configuration in which the front decoration part 232 projects forward from the base part 231, it is preferable that the arrangement density of the openings 211 in the front decoration part 232 (ratio of the opening area to the surface area) is larger than the surrounding base part 231. . In such a configuration, since the front decoration part 232 protrudes from the base part 231, the distance from the filters 30 and 31 is increased. However, since the amount of air sucked from the front decoration 232 is ensured by adjusting the arrangement density of the openings 211, air is uniformly supplied from the center and the end of the front panel 23 to the adsorption deodorizing unit 3. The Thereby, there exists an advantage by which the process of the air by the filters 30 and 31 is performed efficiently.

  In the air cleaner 1, it is preferable that the longitudinal direction of the front panel 23 and the central axes of the curvatures of the plurality of curved surfaces constituting the front panel 23 are substantially parallel. For example, it is preferable that the longitudinal direction of the front panel 23, the central axis of the curvature of the base portion 231 and the central axis of the curvature of the front decoration portion 232 are configured to be substantially parallel (see FIGS. 3 and 4). . In such a configuration, the front panel 23 has a surface shape that extends in the circumferential direction with the longitudinal direction as an axis. Thereby, since the air suction area is secured, there is an advantage that the air suction efficiency is improved.

[Display section]
Moreover, this air cleaner 1 has the display part 7 which displays the driving | running state (refer FIGS. 5-9). The display unit 7 includes a light source 71 and a light guide unit 72 that guides light from the light source 71. The light source 71 is composed of, for example, an LED (light-emitting diode), and is fixedly installed inside the housing 2. The light guide 72 is made of, for example, a transparent acrylic resin, and is embedded in the front panel 23 of the housing 2 so that the display surface 721 can be viewed from the outside of the housing 2. In the display unit 7, the display surface 721 is turned on or off by driving the light source 71, and the operating state of the air cleaner 1 is displayed. The display unit 7 is driven and controlled by the control unit 6.

  The display surface 721 of the display unit 7 is configured to be wide. For example, the light guide portion 72 is formed of a substantially fan-shaped plate-like member, and is guided so that the side surface (display surface 721) of the fan-shaped arc portion is exposed to the outside of the housing 2 (the surface of the front decoration portion 232). The light part 72 is embedded in the front panel 23. And the light source 71 is arrange | positioned in the fan-shaped important position of the light guide part 72. FIG.

  Here, the light guide 72 is subjected to a textured process on a plurality of peripheral surfaces including the display surface 721. Specifically, the peripheral surface visible from the outside of the housing 2 via the display surface 721 is subjected to a graining process. In this embodiment, the display surface 721, the upper surface 722, and the lower surface 723 of the light guide unit 72 are textured. The embossing may be formed on at least a part of these peripheral surfaces 721, 722, and 723, or may be performed on all peripheral surfaces of the light guide unit 72 (not shown). .

  In such a configuration, when the display unit 7 is turned on, light from the light source 71 passes through the light guide unit 72 and is emitted from the display surface 721 to the outside. Thereby, the display surface 721 appears to be lit, and the operating state of the air cleaner 1 can be visually recognized from the outside. Here, since the peripheral surfaces 721, 722, and 723 of the light guide unit 72 are subjected to the texture processing, the light from the light source 71 is diffused in the textured portions. Thereby, since light is effectively irregularly reflected by the light guide part 72, there exists an advantage which the visibility of the display part 7 improves.

  In particular, in the air cleaner 1, the display unit 7 is disposed on the front decoration part 232 of the front panel 23, and the surface of the front decoration part 232 is configured by a curved surface (the front decoration part 232 has a round shape). Have). For this reason, the display surface 721 of the display unit 7 has a wide curved surface shape (see FIG. 5). In such a configuration, in order to improve the visibility of the display unit 7, it is preferable that the display surface 721 is lit at a uniform luminance regardless of the viewing direction when the display unit 7 is lit. In this respect, in the air cleaner 1, since the light from the light source 71 is effectively diffused by the texture processing applied to the light guide unit 72, the visibility of the display unit 7 at the time of lighting is effectively improved. There are advantages to doing.

  In the display unit 7, it is preferable that the width B of the display surface 721 of the light guide unit 72 and the width A of the back surface 724 satisfy B ≧ 2A (see FIG. 8). Thereby, there exists an advantage which the visibility of the display part 7 at the time of lighting improves more effectively.

  Further, in the display unit 7 having the wide display surface 721, there is a possibility that the internal light source 71 can be seen through the display surface 721. Therefore, it is preferable that at least the display surface 721 is subjected to the texture processing. Thereby, the situation where the inner surface of the light guide 72 and the light source 71 inside can be seen from the outside via the display surface 721 is prevented.

  Moreover, in this display part 7, the rib 725 is formed in the upper surface 722 of the light guide part 72, and the nail | claws 726 and 726 are formed in the both ends of the rib 725 (refer FIGS. 7-9). A pair of protrusions 727 and 727 are formed on the lower surface 723 of the light guide portion 72. The rib 725 contacts the inner peripheral surface of the front decoration part 232, the claws 726 and 726 engage with the locking pieces (not shown) of the front decoration part 232, and the protrusions 727 and 727 are on the light source 71 side. The light guide 72 is fixed and held by being sandwiched between the wall surface and the light receiving window 92 (see FIG. 6).

[Operation section]
Moreover, in this air cleaner 1, the operation part 8 is arrange | positioned on the front panel 23 of a housing | casing (refer FIG. 5 and FIG. 10). The operation unit 8 includes an operation button 81, a buffer member 82, and a button cover 83. On the upper surface of the operation button 81, for example, “run”, “stop”, and the like are displayed corresponding to the function. The operation unit 8 transmits the operation signal to the control unit 6 when the operation button 81 is pressed. The buffer member 82 is made of, for example, a sponge material or a rubber material. The button cover 83 is a member that presses the operation button 81 from the front side. A button holding portion 84 is formed on the front panel 23. This button holding part 84 consists of the recessed part and insertion hole which were formed in the upper surface of the front panel 23, for example.

  Here, the operation unit 8 is configured as follows (see FIG. 10). First, the operation button 81 is arranged on the button holding portion 84 of the front panel 23. At this time, the buffer member 82 is disposed between the button holding portion 84 and the operation button 81. Next, the operation button 81 is sandwiched between the button holding portion 84 and the button cover 83. Accordingly, the operation button 81 is pressed and held by the button cover 83.

  In such a configuration, when the operation button 81 is pushed in, the backlash of the operation button 81 is reduced by the buffering action of the buffer member 82. Thereby, there exists an advantage which the operativity of the operation part 8 improves. Further, for example, when the end portion of the operation button 81 is pressed, the pressing force is dispersed and made uniform by the buffering action of the buffer member 82. Thereby, since the operation button 81 is pushed in exactly, there exists an advantage which the operativity of the operation part 8 improves.

  In particular, in recent air cleaners 1, the front panel 23 of the housing 2 tends to be thin, and there may be a case where a sufficient space for arranging the operation unit 8 (operation button 81) cannot be secured. In this respect, the above configuration is preferable in that the operation unit 8 can be arranged in a small space compared to a configuration in which the operation buttons are installed by a hinge structure (not shown).

  In such a configuration, it is preferable that the button holding portion 84 is formed on the base portion 231 of the front panel 23, and the front decoration portion 232 also serves as the button cover 83. Thereby, there exists an advantage by which the number of parts of the operation part 8 is reduced.

[Light receiving section]
Moreover, in this air cleaner 1, the light-receiving part (light receiving element) 91 which receives the operation signal from the outside is arrange | positioned in the housing | casing 2 (refer FIG. 11). For example, the light receiving unit 91 is disposed inside the front panel 23 and below the display unit 7, and is connected to the control unit 6. The housing 2 is provided with a light receiving window 92 at a position corresponding to the light receiving unit 91. The light receiving window 92 is formed, for example, in the front decoration part 232 of the front panel 23 of the housing 2. An operation signal from the outside is received by the light receiving unit 91 in the housing 2 through the light receiving window 92.

  Here, in this air cleaner 1, the light receiving part 91 can receive an operation signal from the outside through the suction port 21 of the housing 2 (see FIG. 11). That is, the light receiving unit 91 can receive an operation signal from the outside not only through the light receiving window 92 but also through the air inlet 21. For example, the front panel 23 of the housing 2 is formed with a plurality of openings 211. And the light-receiving part 91 can receive the operation signal from the outside through a part of these openings 211.

  In such a configuration, since the light receiving unit 91 can receive the operation signal from both the light receiving window 92 and the air suction port, the light receiving range of the light receiving unit 91 can be compared with a configuration in which the operation signal is received only from the light receiving window 92. Has the advantage of being expanded. In addition, such a configuration has an advantage that the degree of freedom in design is high as compared with the configuration in which the light receiving range is enlarged by the large light receiving window 92.

  In the above configuration, the operation signal may be received by the light receiving unit 91 via the light guide unit 72 of the display unit 7 (see FIG. 11).

  Further, in the configuration in which the front decoration part 232 has a curved surface shape (round shape) and protrudes from the base part 231, it is preferable that the light receiving window 92 is formed in the front decoration part 232. Thereby, there is an advantage that the light receiving range of the light receiving unit 91 is further expanded.

Moreover, in this air cleaner 1, the housing | casing 2 consists of resin-type materials. For this reason, the housing | casing 2 is shape | molded by the process by which resin-type material is poured into a metal mold | die via a some flow path. Here, it is preferable that the air suction port 21 (opening 211) is located at a point where the resin-based materials poured into the mold at the time of molding of the housing 2 join (FIG. 12 and FIG. 12). (See FIG. 13).

  In such a configuration, a weld line W is generated in the vicinity of the end of the suction port 21 due to the joining of the resin-based materials. Therefore, there is an advantage that the weld line W generated in the housing 2 can be reduced as compared with a configuration in which the wall surface of the housing 2 is arranged at a point where the poured resin-based materials join together.

  For example, in this embodiment, the base portion 231 of the front panel 23 of the housing 2 is made of a resin material (see FIGS. 12 and 13). In addition, a hollow part for arranging the front decoration part 232 is formed in the center of the base part 231, and a plurality of reinforcing ribs 2311 are arranged in the hollow part. In forming the base portion 231, the resin material is poured into the mold from the positions of the reinforcing ribs 2311. Here, in this base part 231, it is preferable that the slit-shaped opening part 211 (air inlet 21) is located in the middle of the adjacent reinforcement ribs 2311 and 2311.

  In such a configuration, the resin-based materials poured from the adjacent reinforcing ribs 2311 and 2311 flow toward the position of the opening 211 in the mold. Further, since the reinforcing rib 2311 is arranged at the center of the base portion 231, the resin material flows in the mold from the center of the base portion 231 toward the end portion. For this reason, the resin-based material is merged near the opening 211 and at the end of the base 231, and a weld line W is generated at this position. Therefore, this configuration has an advantage that the weld line W generated in the housing 2 can be reduced.

Moreover, in this air cleaner 1, the some vertical rib 2312 is arrange | positioned at the back surface of the base part 231 of the front panel 23 (refer FIG. 14). The vertical ribs 2312 are arranged so as to be orthogonal to the longitudinal direction of the opening 211, and extend in the height direction of the base portion 231 (the height direction in the standing state of the air purifier 1). Yes.

  Here, the base portion 231 is arranged on the upstream side of the pre-filter 30 in the installed state of the front panel 23. At this time, it is preferable that a gap is provided between the vertical beam 311 of the pre-filter 30 and the vertical rib 2312 of the base portion 231 (see FIGS. 14 and 15). In such a configuration, the air sucked from the suction port 21 (the opening 211 of the base portion 231) can flow through the gap between the vertical rail 311 and the vertical rib 2312 to the prefilter 30 side. Therefore, there is an advantage that the air suction efficiency is improved as compared with the configuration in which the vertical bars 311 and the vertical ribs 2312 are close to each other so that the contact or the air flow is hindered.

  In the above configuration, it is preferable that the extending direction of the vertical ribs 2312 of the base portion 231 and the pleating direction of the dust collecting filter 31 are substantially orthogonal (see FIGS. 16 and 17). That is, in the configuration in which the vertical ribs 2312 are provided on the back surface of the base portion 231, the air sucked from the openings 211 of the base portion 231 flows to the dust collection filter 31 side so as to straddle the vertical ribs 2312. For this reason, it is preferable that the pleat direction of the dust collection filter 31 is along the air flow direction across the vertical ribs 2312. Therefore, in the above configuration, air straddling the vertical ribs 2312 smoothly flows along the pleat direction of the dust collection filter 31, so that there is an advantage that air suction efficiency is improved.

[Reinforcement rib structure 3]
Moreover, in this air cleaner 1, the some horizontal rib 2313 is provided in the back surface of the base part 231 of the front panel 23 (refer FIG.14, FIG.18 and FIG.19). These lateral ribs 2313 are provided along the opening 211 of the base portion 231. Further, the lateral rib 2313 is formed so as to be orthogonal to the above-described longitudinal rib 2312.

  Here, the base portion 231 is arranged on the upstream side of the prefilter 30 with the back side facing the prefilter 30 side in the installed state of the front panel 23. At this time, the horizontal ribs 2313 on the back face press and fix the vertical bars 311 of the prefilter 30. Further, the vertical beam 311 of the pre-filter 30 is pressed and fixed to the filter holding member 35 on the downstream side by the horizontal rib 2313.

  In such a configuration, since the vertical beam 311 of the pre-filter 30 is fixed by the pressing of the horizontal rib 2313, the curved deformation of the vertical beam 311 is reduced. Thereby, there exists an advantage by which the position shift of the pre filter 30 is prevented. For example, in a state where the vertical beam 311 is deformed, there is a possibility that a large amount of dust may pass to the subsequent filter (dust collection filter 31 or the like) side through a gap in the deformed portion during operation. That is, the pre-filter 30 at the previous stage does not function effectively. Then, it is necessary to clean the dust adhering to the subsequent filter, and the filter replacement cycle may be shortened. In addition, the above configuration is particularly useful when the vertical beam 311 has a thin and easily bent structure.

  As described above, the air cleaner according to the present invention is useful in that the air suction efficiency can be improved while ensuring the design of the front portion.
