Moreover, even after the mounting, the dust collecting paper 44 is inserted into the convex portion 45a and the recessed portion 43 on the support side and pressed against the recessed portion 43 side, whereby the staggering of the dust collecting paper 44 can be prevented. In addition, since the dust collecting paper 44 is kept in close contact with the collecting electrode plate 42, a gap is formed between the collecting paper 44 and the collecting electrode plate 42, so that the dust collecting ability can be prevented from decreasing. have.

On the other hand, the dust collecting filter 50 disposed on the upper side of the dust collecting unit 40 is mounted to the filter frame 51, it is installed detachably to the main body (1). Between the dust collecting unit 40 and the dust collecting filter 50, the vent 5b which connects to the front opening part 14 mentioned above is located.

As shown in FIG. 6, the handles 51a and 51a which are used when the filter frame 51 is inserted and removed are formed on both sides of the front side of the filter frame 51. As shown in FIG. The dust collecting filter 50 is an electrostatic filter in which a deodorant such as activated carbon is contained in a fibrous material such as an electrostatic nonwoven fabric, and the like is shown in FIG. 6 (FIG. As shown in the figure, in order to increase the dust collecting area, it is folded in a zigzag in the horizontal direction and mounted on the filter frame 51.

On the other hand, as shown in Fig. 5, the ultraviolet lamp unit 60 is housed in a box-shaped unit case 62 in which the ultraviolet lamp 61 is ventilated without the ultraviolet rays leaking outward. It is installed on the installation protrusion member 63 extending from the rear case 2 of the) and is disposed at an approximately center position of the ventilation path to sterilize a part of the air passing through the ventilation path.

That is, the ultraviolet lamp unit 60, as shown in Figs. 16 and 17, has a rod-shaped ultraviolet lamp 61 and a box body 62a which has opened a horizontally long and upper surface for accommodating the ultraviolet lamp 61. And an upper lid 62b covering the upper surface opening of the box 62a.

The box 62a and the upper lid 62b constituting the unit case 62 are made of metal which is not degraded even when irradiated with ultraviolet rays.

An approximately U-shaped incision for supporting both ends of the rod-shaped UV lamp 61 on both side walls on the length side of the box 62a to position the UV lamp 61 in the center of the unit case 62. (notch) 62c, 62c are formed. In addition, both ends of the ultraviolet lamp 61 are provided with collars 61a and 61a which are fitted into the incisions 62c and 62c of the box 62a. When the 61 is provided, the incision 62c is filled to prevent ultraviolet rays from leaking in the direction of the main body side wall. In this way, ultraviolet ray deterioration of the main body side wall formed from synthetic resin is prevented.

The bottom plate 62d and the upper lid 62b of the box 62a are provided with a plurality of protrusion members 62e which are cut inward to surround the ultraviolet lamp 61.

As a result, as shown in FIG. 17, ultraviolet rays (when dotted arrows) emitted radially from the ultraviolet lamp 61 disposed at the center of the unit case 62 do not leak directly to the outside, thereby deteriorating ultraviolet rays of the inner wall of the main body. Is preventing.

In addition, the above-mentioned broken protrusion member 62e is formed in the bottom plate 62d and the hatch cover 62b of the box 62a, so that the corresponding points are cut to form the same number of slits 62f. It is. Thereby, by suction of the blower fan 70, as shown in FIG. 17, the air which passes through the inside of the unit case 62 from the bottom upward (when an arrow of a solid line) is enabled, and passes air It is designed to sterilize.

Although not shown, the inner surface of the unit case 62 is coated with a paint that is hard to reflect ultraviolet rays, for example, a fluorine resin paint. As a result, not only the direct light of the ultraviolet rays but also the reflected light from the inner surface of the unit case 62 and the reflected light from the slits 62f can be prevented, and the ultraviolet ray deterioration of the inner wall of the main body can be prevented more effectively.

In addition, mounting flanges 62h having screw holes 62g are formed at both ends of the rear wall of the box 62a, and the mounting protrusions 63 shown in FIG. 5 are shown in FIG. Likewise, it is installed using screws 64.

A perfusion blower fan 70 is provided on the upper side of the ultraviolet lamp unit 60, and the fan 70 is provided with ribs 2b standing up on the left side of the rear case 2, as shown in FIG. It is rotationally driven by the fan motor 72 provided by the support plate 71 between the side walls.

The other end of the rotating shaft of the fan 70 is freely supported by the bearing 73 provided on the rib 2b provided on the right side of the rear case 2.

Air sucked by the rotation of the blower fan 70 is discharged into the room from the exhaust port 6 formed at the uppermost part of the main body.

Next, operation | movement of this embodiment comprised as mentioned above is demonstrated.

First, dust collection by ion wind operation is demonstrated.

At night, when the air is not contaminated, when the ion wind operation mode is selected by the remote control operation lamp, only the power supply of the high pressure generating device 80 is turned on as the blower fan 70 and the ultraviolet lamp unit 60 are stopped. .

When the high voltage generator 80 is turned on, a high voltage of +6.5 kV is applied to the discharge line 31 of the discharge unit 30, and corona discharge is generated toward the counter electrodes 32 and 32, which are ground electrodes. (Dashed arrow in Fig. 5).

By this corona discharge, the ion wind as shown by the arrow of a one-dot chain line in FIG. 5 is generated, and indoor air is sucked in from the intake port 10 on the lower side of the main body.

The air sucked from the intake port 10 passes through the prefilter 20 to remove relatively large dust, and then enters the discharge unit 30, and the discharge line 31 and the counter electrode 32, 32 are separated from each other. In the air dust in the air is positively charged. The charged dust is attracted to the dust collecting electrode plate 42 which is the ground electrode while passing through the ventilation path of the dust collecting unit 40, and collected on the dust collecting paper 44 covered with the surface.

The dust is removed and cleaned air is passed through the air vent (5b) formed in the front cover (5) between the dust collection unit 40 and the dust collecting filter 50, from the opening opening 14 to the upper side to the room Discharged.

In this manner, since the blower fan 70 or the ultraviolet lamp unit 60 does not operate during ion wind operation, it is possible to collect dust by generating electric power (synergy) with a silent sound.

Moreover, since the opening part 14 which becomes an exhaust port at the time of ion wind operation is formed in the front side of the main body 1, when the main body 1 is used as a wall mount or is attached to a wall, Therefore, even if ions are released by the opening 14, the wall is in a direction falling from the wall so that the wall is not contaminated with ions.

Next, dust collection by fan operation will be described.

If the fan operation mode is selected by the remote control operation during midday or when the air is likely to be polluted, the ultraviolet lamp 61 is energized together with the fan motor 72.

In addition, the high pressure generator 80 is not energized, and the discharge unit 30 is not operated.

When the blowing fan 70 rotates, as shown by the solid arrows in Fig. 5, the suction air causes the air in the upper part of the room to pass through the intake port 10 on the bottom side of the main body. At the time of wind driving, the openings 14 functioning as exhaust ports are respectively sucked into the main body.

The air sucked in from the intake port 10 on the lower side of the main body is removed by the prefilter 20, and then, is passed through the discharge unit 30 and the dust collection unit 40 as it is and is sucked into the dust collection filter 50. In addition, the air in the upper part of the room sucked by the opening 14 formed upward in the front face of the main body is sucked into the dust collecting filter 50 through the air vent 5b formed in the front cover 5. Since the dust collecting filter 50 is an electrostatic filter, fine dust, tobacco smoke, and the like are also collected, and the smell of tobacco and the like is also deodorized with activated carbon.

Part of the air from which fine dust and odors have been removed by the dust collecting filter 50 is led to the ultraviolet lamp unit 60 to be sterilized. The air sterilized by the ultraviolet lamp unit 60 and the air passing through the front and rear are discharged into the room by the upper exhaust port 6 through the blower fan 70. In addition, even if only a part of the air passes through the ultraviolet lamp unit 60, since the unsterilized air is circulated and sucked again, the air of the entire room is sterilized over time.

In this way, since the ultraviolet lamp unit 60 is operated together with the blowing fan 70 during the fan operation, rapid sterilization is possible.

In addition, in addition to the intake port 10 on the lower side of the main body 1 during the fan operation, the opening 14 formed upward in the front face of the main body 1, which was an exhaust port during the ion wind operation, also becomes the intake port. It is possible to remove dust remaining in the lower part of the room, and to effectively remove smoking suspended matter such as tobacco smoke floating in the upper part of the room.

In the above embodiment, only the ion wind operation mode for operating only the discharge unit 30 and the fan operation mode for operating the blower fan 70 and the ultraviolet lamp unit 60 are provided for the sake of simplicity of operation and configuration. In the case of fan operation, a mode in which the discharge unit 30 is operated again may be provided. In this case, since the dust collecting operation differs in the dust collecting unit 40 and the dust collecting filter 50, the dust collecting performance is improved. Improvements can be expected.

In addition, in the above embodiment, a positive high voltage is applied to the discharge line 31, but the same effect can be obtained even when a negative high voltage is applied.

According to the present invention as described above, the intake port on the lower side of the main body is configured to be shared in the ion wind operation and the fan operation, and is connected to the ventilation path between the dust collection unit and the dust collection filter, In the ion wind operation, the exhaust port becomes an inlet port during the ion wind operation and the inlet port becomes the intake port during the fan operation, and the exhaust port during the ion wind operation can be used as the intake port during the fan operation. Both the intake port and the exhaust port serve as the intake port during fan operation, and the effect of minimizing the device as much as that portion is provided.

Further, during fan operation, dust remaining in the lower part of the room can be effectively sucked and removed from the inlet port on the lower side of the main body, and cigarette smoke and the like suspended in the upper part of the room from the opening portion.

In addition, since the opening portion is formed on the front side, when the main body is used as a wall mount or installed near the wall, even if ions are released by ion wind operation, the walls are contaminated with ions because they are separated from the wall. There is no work to do.

In addition, since the opening portion is formed to open upward, tobacco smoke and the like suspended in the upper portion of the room can be sucked and removed more effectively during fan operation.

In addition, the opening portion has a central portion of the front case covering the upper side of the front of the main body in the form of a concave surface, and the central portion of the front cover covering the lower side freely detachable in the form of a convex surface, these concave surface forms and convex Since the gap formed in the shape of the plane is formed by communicating with the ventilation path between the dust collecting unit and the dust collecting filter, the upward opening can be easily formed on the front side of the device without damaging the aesthetics of the device. .
