DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrostatic ion-type air purifier, and more particularly, to an ion-type air purifier having improved workability of replacing a dust collector as a filter.

[0002]

A so-called ion wind type air purifier without a fan utilizing ion wind due to Coulomb force is disclosed in, for example, Japanese Patent Application Laid-Open No. 50-154875. A negative electrode for ionizing the positive electrode and a positive electrode for collecting dust, the dust ionized by the negative electrode is attracted to the positive electrode by Coulomb force, and provided on the negative electrode side near the positive electrode. It is designed to be captured by a filter made of a dielectric material such as dust collecting paper.

Under such circumstances, an invention relating to the shape and arrangement of electrodes for improving the dust collection efficiency of an ion wind type air cleaner has been developed.
It is disclosed in Japanese Patent Publication No. 2-29386. As shown in the perspective view of the periphery of the electrode in FIG. The positive electrode 4 is provided symmetrically. Reference numeral 5 denotes a pair of cathode terminals on which the cathode 3 is extended. As shown in the cross-sectional view of FIG. 7, a front panel 7 having an opening 6 at a portion facing the negative electrode 3 is provided so as to be openable and closable so as to cover the flat plate 2 attached to the wall W. . And the negative electrode 3
The electric lines of force 8 are generated in a wide range inside and outside the purifier main body 1 around the negative electrode 3, and ion wind flows from the opening 6 at the substantially center of the front panel 7 to the outer periphery of the purifier main body 1. By flowing toward the certain opening 9, dust around the purifier main body 1 is efficiently collected by the paper filter 10 which is a dust collecting paper.

[0004] Another type of ion wind type air purifier is disclosed in Japanese Utility Model Publication No. 7-192. This is Figure 8
As shown in FIG. 2, a plurality of needle-shaped negative electrodes 12 are disposed on the outer periphery of a circular base 11, and a belt-shaped negative electrode 12 is provided on the outer periphery of a cylindrical paper container 13 provided inside the negative electrode 12. The positive electrode 14 is provided to constitute the cleaner main body 15, and dust can be collected from the purifier main body 15 from all directions at 360 °. Also, paper container
Inside 13, a dust-collecting paper 16 wound in a roll shape is detachably accommodated, and the leading end of the dust-collecting paper 16 is pulled out from an opening 17 formed on the position side of the paper container 13, and a positive electrode is provided. By wrapping the dust collecting paper 16 around the entire circumference of 14 and fixing the leading end of the dust collecting paper 16 to a suitable place outside the paper container 13 with the stopper 18, the dust ionized by the negative electrode 12 and the positive electrode 14 is captured. It has become.

[0005] By the way, this type of ion air type air purifier is inferior in dust collection efficiency as compared with the conventional air purifier having a fan, but has less noise and power consumption because of the absence of the fan. Since there is also an advantage that ordinary paper can be used and running costs are reduced, a certain degree of clean environment can be obtained by using the paper continuously for a long time, which is recognized in the market. But on the other hand,
Although there is no fan and the structure is simple, there is a problem in that it is difficult to replace the dust collecting paper, and there is a possibility that the apparatus is destroyed, and that design considerations for preventing electric shock are required.

More specifically, in the air purifier shown in FIGS. 6 and 7, the paper filter 10 is provided between the negative electrode 3 and the positive electrode 4, so that a general user can use the paper filter. When replacing the filter 10, open the front panel 7, remove the dirty paper filter 10 while taking care not to disconnect the negative electrode 3, and then replace the new paper filter 10.
Must be attached to the flat plate 2 in close contact with the positive electrode 4, and the front panel 7 must be closed to restart the operation. But wall W
It is extremely difficult to replace the paper filter 10 so that the negative electrode 3 is not disconnected while the purifier body 1 is attached to the printer. In addition, if re-operation is performed with the front panel 7 opened, there is a possibility of electric shock. Therefore, a mechanism that cuts off the negative electrode 3 and the positive electrode 4 in conjunction with opening and closing of the front panel 7 is required separately. It becomes a factor of cost increase.

The air purifier shown in FIG. 8 has a paper container.
Since the paper must be wound around the entire circumference 360 ° of the dust 13, it is difficult to adhere the dust collecting paper 16 to the positive electrode 14, and the dust collecting paper 16
Poor workability when attaching. Further, the dust collecting paper 16 must be fixed to the paper container 13 with a stopper 18 which is a separate member, which causes an increase in cost.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described.
This will be described with reference to the accompanying drawings. In each of these embodiments, the same reference numerals are given to the same parts, and the detailed description of the common parts will be omitted because they are duplicated.

1 to 3 show a first embodiment of the present invention. In FIG. 1, reference numeral 21 denotes a dust-collecting paper formed of, for example, a nonwoven fabric or the like, and an outer peripheral portion of the dust-collecting paper 21 is exchanged between a plastic upper housing 23 and a lower housing 24 constituting a holding member 22. It is pinched as possible. Reference numeral 25 denotes a box-shaped plastic purifier main body, and the holding member 22 includes an opening 26 formed on one side of the purifier main body 25.
Therefore, it is provided detachably in the Z direction shown in FIG. 1 and FIG. On the insertion side of the dust collection paper 21 into the purifier body 25,
Notch 27 is formed so as to lack one side of holding member 22. The notch 27 is for enhancing the adhesion between the positive electrode 31 described later and the dust collecting paper 21. The holding member 22
In the direction of insertion into the purifier main body 25, that is, along one side in the Z direction in the present embodiment, a groove-shaped rail 28 serving as an erroneous insertion prevention means is formed, and corresponding to the rail 28,
A protrusion (not shown) is formed on the inner surface of one side of the cleaner body 25 where the holding member 22 is mounted. That is, rail 28
Are formed asymmetrically with respect to the holding member 22, and the holding member
22 incorrect insertions are prevented. Reference numeral 29 denotes a U-shaped grip portion for improving the workability of inserting the holding member 22.

Reference numeral 31 denotes a belt-shaped positive electrode for dust collection provided on the cleaner body 25 so as to be in close contact with the dust collecting paper 21 when the holding member 22 is mounted. Reference numeral 32 denotes an ionization negative electrode made of, for example, a tungsten wire provided in parallel with and in the same direction as the positive electrode 31. At both ends of the negative electrode 32, terminals 33 for extending the negative electrode 32 inside the cleaner main body 25 are provided. Reference numeral 34 denotes a microswitch as insertion detection means for detecting whether or not the holding member 22 is mounted in the cleaner body 25. The microswitch 34 can be configured to energize the positive electrode 31 and the negative electrode 32 only when the holding member 22 is attached to the cleaner body 25. The configuration of the electrical system around the positive electrode 31 and the negative electrode 32 is omitted here.

The reason for bringing the dust-collecting paper 21 and the positive electrode 31 into close contact with each other is that if electrons emitted from the negative electrode 32 accumulate on the dielectric dust-collecting paper 21 without being absorbed by the positive electrode 31, the positive electrode 31 is positively charged. This is because the electric field intensity between the electrode 31 and the negative electrode 32 is weakened, and as a result, the ion wind is also weakened and the dust collecting effect is reduced. That is, the dust collection paper 21
And the positive electrode 31 must be brought into close contact with each other, and electrons remaining on the dust-collecting paper 21 must be released to the positive electrode 31 as soon as possible. And
The dust ionized by the negative electrode 32 is captured by the dust-collecting paper 21, and only clean air circulates from the cleaner body 25 to the outside.

As shown in FIG. 2, since the holding member 22 is detachable from one side of the purifier main body 25, that is, from the opening 26, the dust collecting paper can be held even when the purifier main body 25 is hung on the wall. 21 can be replaced. FIG. 3 shows a cross-sectional view of the device when it is hung on a wall.
And a front cover 43 provided so as to cover the opening front part of the purifier main body 25. Reference numeral 43 denotes a mounting bracket for mounting the purifier main body 25 to an arbitrary wall W. In this embodiment, since the purifier main body 25 is attached to the vertical surface of the wall W by the mounting bracket 43, the ion wind I indicated by the arrow flows through the opening formed between the purifier main body 25 and the cover 41. After passing through the cleaner 44, it flows upward from the lower side of the purifier body 25 and circulates in the room.

As described above, according to the present embodiment, in an ion wind type air purifier in which dust collected and ionized by the positive electrode 31 for dust collection and the negative electrode 32 for ionization is captured by the dust collecting paper 21, A holding member 22 capable of exchanging the dust collection paper 21 outside the purifier main body 25 is provided detachably on the purifier main body 25.
For this reason, even if the purifier main body 25 is hung on the wall W, the user can easily replace the dust collector paper 21 by simply removing the holding member 22 together with the dirty dust collecting paper 21 from the purifier main body 25. Can be easily performed. Also,
Both the positive electrode 31 and the negative electrode 32 are provided in the purifier main body 25, and do not touch the vicinity of the positive electrode 31 and the negative electrode 32 when the dust collecting paper 21 is replaced. A special mechanism for preventing electric shock, which cuts off electricity through the negative electrode 3 and the positive electrode 4 in conjunction with opening and closing of the front panel 7, becomes unnecessary. Further, in this case, since the wire-shaped negative electrode 32 is in the cleaner main body 25, there is no danger that the negative electrode 32 will be disconnected by mistake when the dust collecting paper 21 is replaced. In other words, the dust collector 21 can be easily replaced without damaging the positive electrode 31 and the negative electrode 32, and the cost can be reduced even if the device is hanged on the wall. It is possible to provide an ion-air-type air purifier that does not have a risk of breaking the thin wire-shaped negative electrode 32.

In this embodiment, a rail 28 as an erroneous insertion preventing means for preventing erroneous insertion of the holding member 22 is provided so that the holding member 22 is not inserted into the opening 26 of the purifier main body 25 from an erroneous direction. It is provided. Therefore, even if the user does not correctly understand the insertion direction of the holding member 22, the holding member 22 will not be erroneously inserted into the cleaner body 25, and the erroneous insertion of the holding member 22, for example, breakage of each part, etc. Can be eliminated. In addition, as the erroneous insertion preventing means, a convex portion or a step portion may be provided asymmetrically on the holding member 22 instead of the groove-shaped rail 28 in the present embodiment.

In the present embodiment, the holding member 22 is a
A micro switch 34 is provided as insertion detection means for detecting whether or not the device is mounted inside. Therefore, the micro switch 34 can be configured to energize the positive electrode 31 and the negative electrode 32 only when the holding member 22 is attached to the cleaner main body 25. It is possible to prevent unnecessary power consumption.

Next, a second embodiment of the present invention will be described with reference to FIG. The drawing shows a state in which the dust collecting paper 21 is attached to the holding member 22. However, unlike the first embodiment, the holding member 22 is formed of a single housing, and the end of the dust collecting paper 21 is Pressing portions 52 having slits 51 for pressing are provided on both upper and lower sides of the holding member 22. In the present embodiment, the positive electrode 31 that is in close contact with the dust-collecting paper 21 is provided not on the cleaner main body 25 but on the holding member 22. A connection portion 53 for applying a high voltage from the cleaner main body 25 is provided on the tip side of the positive electrode 31, that is, on the side of the insertion direction into the cleaner main body 25. The connecting portion 53 is formed by bending the tip of the positive electrode 31 extending from the side surface of the holding member 22. The purifier body 25 is a positive electrode
It has the same configuration as that of the first embodiment except that the terminal 31 is not provided and a terminal (not shown) that comes into contact with the connecting portion 53 when the holding member 22 is inserted is provided. I have.

In this embodiment, the dust ionized by the positive electrode 31 for dust collection and the negative electrode 32 for ionization is used to collect the dust 21
In the ion wind type air purifier captured by the
A holding member 22 for exchanging the dust-collecting paper 21 outside the cleaning device 25 is detachably provided on the cleaner main body 25.
Is provided. Therefore, in this case, the effect in the first embodiment, that is, even if the device is kept hanging on the wall,
In addition to providing an ion wind type air purifier that can easily replace the dust collecting paper 21 and reduce the cost, and that is not likely to disconnect the fine wire-shaped negative electrode 32 by mistake. In addition, there is an advantage that the work of replacing the dust collecting paper 21 can be performed while checking the adhesion between the dust collecting paper 21 and the positive electrode 31.

Next, a third embodiment of the present invention will be described with reference to FIG. The holding member 22 is formed of a single casing as in the second embodiment, but one of the holding portions 52 has
Instead, a support member 61 for supporting both ends of the negative electrode 32 for ionization is provided. Although not shown, a terminal for applying a voltage to the negative electrode 32 is connected to the holding member 22.
When the holding member 22 is mounted on the purifier main body 25, it comes into contact with a power supply terminal provided in the purifier main body 25. The other points have the same configuration as that of the second embodiment.

In the present embodiment, the positive electrode 31 and the negative electrode 32 are provided on the holding member 22. In this case, when replacing the dust collecting paper 21, it is necessary to pay some attention so as not to break the thin wire-shaped negative electrode 32, but replace the dust collecting paper 21 from the conventional cleaner body 25 hung on a wall. The dust collection paper 21 can be replaced much more easily than the one used. Also, if the holding member 22 is taken out from the purifier body 25,
Since the energization of the positive electrode 31 and the negative electrode 32 is cut off, no special mechanism for preventing electric shock is required, and the cost can be reduced. In addition, since the positive electrode 31 and the negative electrode 32 are provided on the holding member 22 side, not only the replacement of the dust collecting paper 21 but also cleaning around the positive electrode 31 and the negative electrode 32 and other maintenance are performed outside the purifier main body 25. There is an advantage that it can be easily performed. Further, as in the second embodiment, the work of replacing the dust collecting paper 21 can be performed while checking the adhesion between the dust collecting paper 21 and the positive electrode 31.
