  FIG. 1 is a perspective view of an air cleaner according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of the air cleaner shown in FIG. FIG. 3 is a schematic diagram of the air cleaner shown in FIG. 1. 4 is an exploded perspective view of the air cleaner shown in FIG. FIG. 5 is a perspective view of the panel of the air cleaner shown in FIG. 1 as viewed from the back side, and FIGS. 6 and 7 are perspective views of the rectifying guides of the air cleaner shown in FIG. 1, respectively. Hereinafter, with reference to FIGS. 1-7, the air cleaner 1 of this embodiment is demonstrated in detail.

  The air purifier 1 sucks indoor air and cleans it to improve indoor comfort. Specifically, the air purifier 1 has dust (house dust, pollen, pet hair, tick droppings and dead bodies, mold spores, etc.) and odors (cigarette smoke, germs, viruses, Clean automobile exhaust gas, pet odor, mold odor, etc.) This air cleaner 1 is normally used in the state mounted on the floor surface.

  The air cleaner 1 of this embodiment is provided with the main-body part 10, the panel 20 attached to the front surface of the main-body part 10, and the rectification | straightening guide 30 attached to the back surface of the panel 20, as shown in FIGS. ing. The main body 10 mainly includes a casing 11, a fan motor 12, a blower fan 13, and an air cleaning unit 14.

  The casing 11 houses the fan motor 12, the blower fan 13, the air cleaning unit 14, and the like inside. Side air inlets 11 a for sucking room air are provided on both side surfaces of the casing 11. Moreover, the top surface part of the casing 11 is provided with the blower outlet 11b, and the air purified by passing through the air cleaning unit 14 is blown upward through the blower outlet 11b.

  The fan motor 12 is a drive source of the blower fan 13, and the blower fan 13 sucks room air through the side suction port 11a and suction ports 21a and 22a described later, and is purified through the blower port 11b. It has a function to blow out the air.

  An air cleaning unit 14 through which air sucked by the blower fan 13 passes is disposed upstream of the blower fan 13. The air cleaning unit 14 is provided to remove various dusts such as mold, pollen, and house dust floating in the air. As shown in FIG. 4, the air cleaning unit 14 includes a prefilter 41, a plasma ionization unit 42, a photocatalytic filter 43, a plasma catalytic filter 44, and a streamer discharge unit 45.

  The pre-filter 41 is provided behind the panel 20 so as to face the panel 20 and collects relatively large dust and dust. The pre-filter 41 includes a net made of a polypropylene-like (hereinafter referred to as PP) thread-like resin net and a frame that holds the net. The fiber constituting the net of the pre-filter 41 may be supported so that both or either of the photocatalyst and the catechin are exposed to the air side. The photocatalyst contains titanium oxide or the like whose photocatalytic action is activated by ultraviolet rays, and removes fungi and viruses such as fungi and bacteria contained in dust attached to the prefilter 41. Catechin is a kind of polyphenol and is a generic name for epicatechin, epigallocatechin, epicatechin gallate, epigallocatechin gallate, and the like. This catechin suppresses the growth of fungi such as fungi or bacteria contained in the dust adhering to the prefilter 41, or inactivates viruses.

  The plasma ionization unit 42 is provided on the downstream side of the prefilter 41. The plasma ionization unit 42 charges relatively small dust floating in the air that has passed through the prefilter 41.

  The photocatalytic filter 43 is provided on the downstream side of the plasma ionization unit 42. The photocatalytic filter 43 is formed in a pleat shape, and is formed by bonding an electrostatic filter and a titanium apatite-carrying filter. The photocatalytic filter 43 is arranged so that the electrostatic filter is on the upstream side and the titanium apatite-carrying filter is on the downstream side. The electrostatic filter adsorbs dust or the like charged when passing through the plasma ionization unit 42. The titanium apatite-carrying filter adsorbs dust or the like that has passed through the electrostatic filter. This titanium apatite-carrying filter is formed of PP fibers carrying titanium apatite, like the pre-filter 41. Titanium apatite is apatite in which some calcium atoms of calcium hydroxyapatite are replaced with titanium atoms by a technique such as ion exchange. This titanium apatite has the property of specifically adsorbing viruses, molds, bacteria, etc. contained in dust and the like. The titanium apatite has a photocatalytic function activated by active species supplied from a streamer discharge unit 45 described later, and inactivates or kills viruses, molds, bacteria, and the like. In addition, since the photocatalytic filter 43 is formed in a pleat shape, it can be easily folded according to the crease.

  The plasma catalyst filter 44 is provided on the downstream side of the photocatalyst filter 43. The plasma catalyst filter 44 carries anatase type titanium dioxide. The plasma catalyst filter 44 adsorbs viruses and fungi in the air that have not been adsorbed by the photocatalytic filter 43. In the plasma catalyst filter 44, the adsorbed bacteria and viruses are killed or inactivated by the titanium dioxide activated by the active species.

  The streamer discharge unit 45 blows out radical species such as high-speed electrons, ions, ozone, and hydroxy radicals having a strong decomposing power. As a result, small organic molecules such as ammonia, aldehydes, nitrogen oxides in the air are decomposed and / or deodorized, and the prefilter 41 is sterilized.

  The panel 20 is attached to the front surface of the casing 11 so as to cover the front opening of the casing 11. In the present embodiment, as shown in FIGS. 3 and 5, the width direction (X direction) of the panel 20 is the longitudinal direction in the region near the lower end portion of the front surface portion 21 of the panel 20 and facing the prefilter 41. A rectangular front suction port 21a is provided. Specifically, the front suction port 21 a is a region inside the lower side 1/3 of the height direction (Y direction) of the panel 20, and is a lower half of the height direction of the prefilter 41. It is formed so as to face the region (except for the lower 1/10 region). In the present embodiment, the bottom surface portion 22 of the panel 20 is provided with two bottom surface suction ports 22 a along the width direction (X direction) of the panel 20. The opening area of the bottom surface suction port 22a can be increased if the depth (Z direction) of the panel 20 (bottom surface portion 22) is large, but in recent years when a thin air cleaner is preferred. Since there is a restriction on the depth of the panel 20 (bottom surface portion 22), it is difficult to secure the opening area of the bottom surface suction port 22a. Further, a boss cover 23 for fastening a screw for fixing the rectifying guide 30 to the panel 20 is provided between the two bottom suction ports 22a on the bottom surface 22. In addition, two boss portions 24 for fastening screws for fixing a rectifying guide 30 to be described later to the panel 20 are provided on the rear surface of the panel 20 at a predetermined interval in the width direction (X direction). ing. In this embodiment, since the strength of the lower part of the panel 20 is reduced due to the formation of the front suction port 21a and the bottom suction port 22a, there is a concern that the panel 20 bends when the screws are fastened. The boss portion cover 23 and the boss portion 36 (see FIGS. 6 and 7) provided on the rectifying guide 30 are fastened with screws, so that bending of the panel 20 can be suppressed.

  As shown in FIGS. 6 and 7, the rectifying guide 30 includes a guide portion 31 having a function of guiding air sucked from the front suction port 21a and the bottom suction port 22a to the prefilter 41 through different flow paths, An opening forming portion 32 is formed which extends from the upper end of the guide portion 31 to the back surface of the front surface portion 21 of the panel 20 and has an opening 33 serving as a flow path for air sucked from the front suction port 21a. As shown in FIG. 3, the guide portion 31 is inclined in a direction away from the panel 20 from the lower side to the upper side of the panel 20, and the air sucked from the front suction port 21a flows along the surface thereof. Air sucked from the bottom suction port 22a flows along the back surface. Thereby, the air sucked from the front suction port 21a and the bottom suction port 22a travels toward the prefilter 41 without colliding in the device. Moreover, the opening formation part 32 is comprised by the convex-shaped curved surface toward upper direction. A lattice 34 is provided in the opening 33 of the opening forming portion 32. And the opening 33 in which this grating | lattice 34 is provided is arrange | positioned upwards rather than the front suction inlet 21a. Further, the rectifying guide 30 has two boss portion covers 35 for fixing the rectifying guide 30 to the two boss portions 24 provided on the back surface of the panel 20 on the two boss portions 24 (see FIG. 5). It is provided to correspond.
