DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described in detail based on an embodiment.
[0027]

[0029]
An overall kamaboko-shaped casing 11 that defines the overall shape of the apparatus main body 10 has an opening 12 on the front surface. Further, a fan 13 including a drive motor (not shown) (a cross flow fan is used in the present embodiment) is provided inside the opening 12 of the casing 11, and a discharge port 14 is formed in the upper portion of the casing 11 in the figure. ing. Further, three contact springs 15 for supplying a voltage to an ionizer and a collector of the charge collection unit 30 described later are provided in the opening 12, and are connected to these contact springs 15 in the casing 11. A voltage application means (not shown) is incorporated.
[0030]
In addition, the first locking groove 16 and the second locking groove 17 for mounting and holding the charge collecting portion 30 on both side walls in the width direction (left and right direction in FIG. 3) in the opening portion 12 of the casing 11. In the second locking groove 17, a fixed spring 18 for holding the mounted charge collecting portion 30 is provided. Furthermore, mounting grooves 19 for mounting the lid 50 are provided on both sides in the width direction of the lower portion of the opening 12 in the drawing. A support bar 20 that rotatably supports the lid 50 is provided at the lower portion of the mounting groove 19 in the figure, and two locking ridges 21 are provided on the outer side wall in the mounting groove 19. It has been. Further, locking holes 22 for engaging and holding the lid 50 are provided on both sides in the width direction of the upper portion of the opening 12 in the drawing and on the outside of the second locking groove 17. Further, an abutment protrusion 25 is provided on the upper peripheral edge of the opening 12 to abut on a handle metal fitting 35 to be described later to rotate and store the handle metal fitting 35.
[0031]
On the other hand, the electrification collection part 30 has a shape that can be mounted so as to surround the fan 13 in the opening part 12 of the casing 11 by forming a substantially semi-cylindrical shape overall. Although the details are omitted, the curved front surface has a suction port 31, in which a pre-filter, an ionizer as a charging unit, and a collector as a collection unit are sequentially built, and the back side Is equipped with an ozonolysis type deodorizing filter. Accordingly, when dust-containing air or the like is fed from the suction port 31, clean air from which dust has been removed is discharged from the back side. Although not shown, a contact portion for connecting the above-described ionizer and collector to the electrode 15 of the apparatus main body 10 is provided on the outer peripheral surface of the charge collecting portion 30. Furthermore, a first locking projection 32 and a second locking projection 33 for mounting in the opening 12 of the casing 11 are provided on both side walls of the charge collection unit 30.
[0032]
Here, the ionizer and the collector are formed by a combination of a discharge electrode member, a counter electrode member, and a high voltage electrode member, and the counter electrode member has a volume resistivity of 10 ⁷ It is made of a conductive resin material of Ωcm or less, and the high-voltage electrode member has a volume resistivity of 10 ¹⁰ -10 ¹³ It is preferable to form a semiconductive resin material of Ωcm. In this case, the ionizer is composed of a combination of a discharge electrode member and a counter electrode member, and the collector is composed of a combination of a counter electrode member and a high voltage electrode member. Preferably, each discharge electrode member, the counter electrode member, and the high-voltage electrode member are each integrally formed into a shape having a plurality of substantially arc-shaped comb teeth by combining the respective materials. It is preferable to constitute a collector.
[0033]
Here, the counter electrode members and the high-voltage electrode members are parallel to each other, and are required to be alternately arranged in parallel and at equal intervals. In the case of the electric dust collection method, the counter electrode member and the high-voltage electrode member make the electric field intensity uniform (the distance between the electrodes at the upstream and downstream positions of the airflow is uniform) to ensure dust collection efficiency. Therefore, when the cross flow fan as in the present invention is used from the relationship of ventilation resistance, each of the substantially arc-shaped electrode plates is in the axial direction of the fan 13. It is convenient to arrange them so as to be orthogonal to each other. Thereby, the air flow rate between the electrode plates can be made the same level, the ventilation resistance can be reduced, and the dust collection performance of each electrode plate can be used effectively.
[0034]
In the ionizer and collector configured in this way, even if conductive dust is mixed in the particles charged by the ionizer, the movement of the charge of the high-voltage electrode member is limited by the resistance of the semiconductive resin material. Sparks can be prevented from occurring between the high-voltage electrode member and the counter electrode member of the dust collector.
[0035]
A handle metal fitting 35 is attached to one end of the back surface of the charge collecting unit 30. The details of the handle fitting 35 will be described with reference to FIG. 5, which is a rear view of the charge collecting portion 30, FIG. 6, which is a side view, and FIG.
[0036]
The handle fitting 35 has a gripping portion 35a having a width that can be gripped by a human hand, and can be gripped by a human hand by bending in a direction substantially perpendicular to both longitudinal ends of the gripping portion 35a. A first connecting portion 35b having a length is provided. The end of the first connecting part 35b has a second connecting part 35c that is orthogonal to the first connecting part 35b and the gripping part 35a and does not coincide with the longitudinal direction of the gripping part 35a. Shaft portions 35d and 35e extending in a substantially orthogonal direction and extending in the longitudinal direction of the gripping portion 35a are provided on the portion 35c. Here, one shaft portion 35d is longer than the other shaft portion 35e. The tip portions of the shaft portions 35 d and 35 e are pivotally attached to bearing portions 37 </ b> A and 37 </ b> B that are through holes formed integrally with the outline of the charge collection portion 30. At this time, the widths of both ends of the shaft portions 35d and 35e are substantially the same as the distance between the outer end portions of the bearing portions 37A and 37B. A stopper 38 is provided outside the one bearing portion 37A. Similarly, the stopper 38 is an elastic piece integrally formed on the outer surface of the charge collecting portion 30, and the tip portion normally closes the through hole of the bearing portion 37 </ b> A. 35d is allowed to pass through the bearing portion A.
[0037]
Accordingly, the longer shaft portion 35d is inserted into the bearing portion 37A (FIG. 7A), and the stopper 38 is elastically deformed to insert the shaft portion 35d to the back (FIG. 7B). When the shaft portion 35e is inserted into the bearing portion 37B, the stopper 38 returns to its original position, and the handle fitting 35 is rotatably mounted on the bearing portion 37B (FIG. 7C).
[0038]
Further, as shown in FIG. 8, the handle fitting 35 attached in this way has a strength capable of supporting the entire electrification collecting unit 30 by gripping the handle fitting 35. Further, the handle fitting 35 is stored along the outer wall of the charge collection unit 30 when the charge collection unit 30 is mounted on the casing 11. That is, as shown in FIG. 9, when the charge collection part 30 is mounted on the casing 11, the grip part 35 a and the first connection part 35 b of the handle fitting 35 are connected to the handle fitting 35 of the charge collection part 30. It is held along the upper wall adjacent to the attachment. That is, the length of the second connecting portion 35c that connects the first connecting portion 35b and the shaft portions 35d and 35e is set to substantially match the distance from the bearing fittings 37A and 37B to the end portions on the back surface. ing. In the present embodiment, the handle metal fitting 35 can be automatically stored as described later.
[0039]
This will be described with reference to FIGS.
[0040]
When such a charge collecting part 30 is attached to the apparatus main body 10, as shown in FIG. 10, the charge collecting part 30 is lowered by the handle fitting 35 and the inside of the opening 12 of the casing 11 from the lower end part. First, the first locking protrusion 32 at the lower side of the side wall of the charge collecting portion 30 is inserted up to the protrusion receiving portion 16 a of the first locking groove 16. Further, the electrification collecting portion 30 is rotated around the protrusion receiving portion 16a (see FIGS. 2 and 11). As a result, the second locking protrusion 33 is inserted into the second locking groove 17, and at this time, one second connecting portion 35 c of the handle fitting 35 starts to contact the contact protrusion 25 (FIG. 12). ). When further rotated, the second locking projection 33 is inserted while elastically deforming the fixing spring 18 and is fixedly held by the fixing spring 18 (see FIG. 2), and the grip portion 35a of the handle fitting 35 and the first connection are connected. The portion 35b is stored in a state of being in close contact with the upper wall of the charge collecting portion 30 by being pressed by the contact protrusion 25 that is in contact with the connecting portion 35b (see FIG. 13).
[0041]
Here, the second connecting portion 35c adjacent to the long shaft portion 35d and the contact protrusion 25 are aligned so that they come into contact with each other. However, the first connecting portion 35b extends from the bearing portion 37A. Since the contact protrusion 25 exists at a relatively distant position, even if the contact protrusion 25 has a certain width, the contact protrusion 25 does not contact the bearing portion 37A, and alignment is relatively easy.
[0042]
Further, since the second locking projection 33 of the charge collection unit 30 is fixedly held by the fixing spring 18 in such a state that the contact projection 25 is in contact with the first connecting portion 35b, FIG. As shown in the figure, when the handle bracket 35 is raised, the electrification collecting portion 30 is rotated by using the contact portion between the contact protrusion 25 and the second connecting portion 35c as a fulcrum by the lever principle. The protrusion 33 is released from the fixed spring 18. Therefore, the charge collection unit 30 can be detached from the casing 11 relatively easily.
[0043]
At this time, the release of the second locking projection 33 from the fixing spring 18 by raising the handle fitting 35 is only one side on the side where the contact projection 25 is provided, and the position offset from the center of the casing 11. Thus, for example, even if the handle is attached to a high place in an upside-down state, the charge collector 30 does not fall off simply by raising the handle bracket 35. That is, since the contact protrusion 25 is only on one side, when the handle 35 is raised, one of the second lock protrusions 33 on the left and right sides of the second lock protrusion 33 on the left and right sides is the second lock protrusion. Only 33 is released from the fixed holding by the fixing spring 18 and the other second locking projection 33 remains fixed and held by the fixing spring 18 so that it does not fall off but can be removed with a light force. The abutment protrusion 25 may be provided so as to abut both of the second connecting portions 35c. However, only one of the abutment protrusions 25 is sufficient to obtain the above-described action, and rather, only one of the abutments is safer. Excellent in terms of sex.
[0044]
On the other hand, the lid 50 is detachable from the casing 11 and opens and closes the opening 12, and a suction port 51 facing the suction port 31 of the charge collection unit 30 is formed on the entire surface. On both sides in the width direction of the lower portion of the lid 50 in the drawing, gripping portions 52 that grip the support bar 20 of the casing 11 are provided. Further, a thin plate-like stay portion 53 to be inserted into the mounting groove 19 of the casing 11 is protruded on the upper side in the vicinity of the grip portion 52, and the engagement in the mounting groove 19 is provided outside the tip portion of the stay portion 53. A cylindrical locking projection 54 that can be engaged with the protrusion 21 is provided. In addition, on the outside of the stay portion 53, there is a finger placement index when the stay portion 53 is elastically deformed in the thickness direction in order to release the locked state of the locking projection 54 and the locking protrusion 21. The finger placing portion 55 is provided. On the other hand, a locking claw 56 that is inserted into and engaged with the locking hole 22 of the casing 11 protrudes from the back side of the upper portion of the lid 50 in the figure. Therefore, when attaching / detaching and opening / closing the lid 50, if the lid 50 is rotated with the support bar 20 inserted into the grip 52, the grip 52 grips the support bar 20 in a freely rotatable manner and removes it. It becomes impossible to separate. In this state, when the lid 50 is rotated in the closing direction, the locking projection 54 of the stay portion 53 comes into contact with the first locking protrusion 21. Here, when the stay portion 53 is elastically deformed inward and the locking projection 54 is moved over the first locking projection 21, the locking projection 54 is positioned between the two projections 21, This state is maintained. Further, when the lid 50 is rotated in the closing direction while elastically deforming the stay portion 53 inward from this state, the locking projection 54 gets over the second locking protrusion 21 and the positioning holding state is released. .
[0045]
Here, the outer side surfaces of the two locking ridges 21 are inclined surfaces 21a whose height is lower toward the outer side, and the inner side is a vertical surface 21b. Moreover, since the latching convex part 54 moves in an arc-shaped locus with the rotation of the lid 50, it has a cylindrical shape. Therefore, in the case of movement in a direction in which the locking projection 54 enters between the locking projections 21, the cylindrical locking projection 54 can easily get over the inclined surface 21a, and the stay portion 53 is not necessarily provided. There is no need for elastic deformation. On the other hand, the movement in the direction in which the locking projections 54 come out from between the locking protrusions 21 is restricted by the vertical surface 21b, and the positioning holding state cannot be released without elastically deforming the stay portion 53. The state is reliably maintained. Moreover, after the latching convex part 54 gets over the two latching protrusions 21, it can be freely rotated until the cover body 50 is completely closed, and the latching pawl 56 is inserted into the latching hole 22 (see FIG. 3), and the lid 50 is slightly elastically deformed along the bending direction by pushing the open / close end of the lid 50, preferably the pressing portions 57 on both sides or the vicinity thereof, and the locking pawl 56 Engages with the locking hole 22.
[0046]
The air cleaning device of the present embodiment described above can reduce the dead space in the substantially cylindrical casing 11 as much as possible to achieve compactness, maximize the suction area of dust-containing air, and reduce airflow loss. There is an effect that it can be reduced.
[0047]
In particular, the handle fitting 35 and the attachment structure of the handle fitting 35 have the following features.
[0048]
First, since one shaft portion 35d of the handle fitting 35 is lengthened so as to be able to pass through the bearing portion 37 and the stopper 38 is provided outside the one bearing portion 37, the attachment of the handle fitting 35 is very easy. became.
[0049]
Further, by providing the contact protrusion 25 on the casing 11 facing the second connection portion 35 c of the handle metal fitting 35, the second connection portion 35 c becomes the contact protrusion 25 when the charge collection portion 30 is mounted. The handle metal fitting 35 is automatically stored by abutting and does not obstruct the closing of the lid 50. On the other hand, when the charge collection unit 30 is taken out, the handle metal fitting 35 is raised, so that the second engagement of the charge collection unit 30 with the contact portion between the second connection portion 35c and the contact protrusion 25 as a fulcrum. Since the stop protrusion 33 is released from the fixed spring 18, the removal operation is facilitated. At this time, since the contact between the contact protrusion 25 and the second connecting portion 35c is only on one side, there is no risk of the charge collection portion 30 dropping off, but one side is removed. Easy to remove.
[0050]
As described above, the handle fitting and the mounting structure thereof according to the above-described embodiment do not take up an extra space when the charge collecting unit 30 is mounted, and can be easily gripped during use. This also has the effect of assisting in the removal.
[0051]
For comparison, as shown in FIG. 15, when a locking projection 81 for removing the abutting projection 25 and holding the handle fitting 35 along the upper wall of the charge collecting portion 30A is provided, the gripping portion 35a is provided. And engagement with the locking projection 81 did not work. That is, since the positioning of the two cannot be performed with high accuracy, the two do not engage with each other, or the engagement between the two is too difficult to disengage.
[0052]
For comparison, as shown in FIG. 16, the handle 83 is provided integrally with the outer shell of the charge collection unit 30 </ b> B. In this case, a space for storing the handle 83 is provided in the opening 12 of the casing 11. Since it is necessary to ensure, the size of the main body of the electrification collecting unit 30B becomes relatively remarkably small. Thus, when the size of the electrification collecting portion 30B is reduced, the electrode plate, that is, the electrode plate area is reduced, and the dust collection area is reduced. Therefore, performance degradation as an air cleaning device cannot be avoided, and it is not preferable as an air cleaning device for the purpose of downsizing.
[0053]
The air cleaning device 1 according to the embodiment described above can be stably installed in an empty space on the upper surface 111a of the rocker 111, for example, as shown in FIG. 17 (a), or the leg 1a, as shown in FIG. 17 (b). It is possible to put up and put up and to effectively use the space. In this case, even if it is arranged on the upper surface of a higher rocker, stability can be ensured and clean air can be diffused over a wide range without disturbing the flow of room air.
[0054]
Further, as shown in FIG. 18 (a), the air purifier 1 having the legs 1a can be set up on the floor, and as shown in FIG. 18 (b), a flange 1b is attached to one end portion in the width direction to vertically It can also be placed, and can be installed at the corner of the room by attaching a flange 1c only on the front surface as shown in FIG. 18 (c). Moreover, as shown in FIG. Can be installed in narrow spaces. Further, as shown in FIG. 19A, for example, it can be installed horizontally on the window 113 or the like, and can be installed vertically on the side of the window 113 as shown in FIG. In addition, when installing sideways like Fig.19 (a), it can install also upside down.
[0055]
The air purifying apparatus of this embodiment can perform the opening / closing operation | movement of the cover body 50, and the attachment / detachment operation | movement of the electrical charge collection part 30 as above-mentioned in any installation aspect mentioned above.
[0056]
