Further, a fan 13 including a drive motor (not shown) is provided inside the opening 12 of the casing 11 (in this embodiment, a cross flow fan is used), and a discharge port 14 is formed in the upper part of the casing 11 in the figure. ing. Furthermore, three electrodes 15 for supplying a voltage to an ionizer and a collector of a charge collection unit 30 to be described later are provided in the opening 12, and the casing 11 is connected to these electrodes (not shown). Voltage application means is built-in.
[0027]
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 is provided for holding the mounted charge collecting portion 30. 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. The casing 11 has a built-in malfunction prevention switch that restricts the operation of the apparatus when the lid 50 is open, and a switch opening 23 for releasing the malfunction switch. .
[0028]
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.
[0029]
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 is formed of a conductive resin material having a volume specific resistance value of 10 ⁷ Ωcm or less. Is preferably made of a semiconductive resin material having a volume resistivity of 10 ¹⁰ to 10 ¹³ 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.
[0030]
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.
[0031]
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.
[0032]
The lid 50 is detachable from the casing 11 and opens and closes the opening 12, and a suction port 51 that faces the suction port 31 of the charge collection unit 30 is formed on the entire surface. With reference to FIG. 5 showing a front view of the lid body, a side view thereof, a cross-sectional view taken along line BB and a cross-sectional view taken along line CC of FIG. This will be described in detail.
[0033]
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 a locking hole 22 that penetrates the casing 11 protrudes from the back side of the upper portion of the lid 50 in the figure. Further, on the front side facing the locking pawl 56, when the locking pawl 56 and the locking hole 22 are engaged, or when the lid 50 is elastically deformed along the bending direction in order to release the engaged state. A pressing portion 57 is provided as an index for placing the finger. A release protrusion 58 that can be inserted into the switch opening 23 of the casing 11 is erected on one side end of the back surface side of the lid 50. When the lid 50 is opened, the release protrusion 58 is formed. Even if the malfunction prevention switch is moved away from the malfunction prevention switch, that is, the malfunction prevention switch is activated and the operation switch is accidentally turned on in that state, the air purifier is not operated, and is released when the lid 50 is closed. The protrusion 58 pushes the malfunction prevention switch, that is, the malfunction prevention switch is released, so that the air cleaning device 1 can be operated.
[0034]
Next, the attaching / detaching and opening / closing mechanism of the lid 50 will be further described in detail with reference to FIGS. 7 to 9 showing the movement state of the lid when the lid 50 is opened and closed.
[0035]
The inner diameter of the grip portion 52 of the lid 50 is slightly larger than the outer diameter of the support bar 20, and the opening size of the opening 52 a of the grip portion 52 is slightly larger than the size between the opposing flat portions 20 a of the support bar 20. . Therefore, when the opening 52a of the grip portion 52 is coincident with the flat portion 20a of the support bar 20, that is, when the opening 52a of the grip portion 52 is directed upward in FIGS. The support bar 20 can be attached and detached. When the lid 50 is rotated with the support bar 20 inserted into the grip portion 52, the grip portion 52 grips the support bar 20 in a rotatable manner and cannot be detached. A partially enlarged view at this time is shown in FIG. When the lid 50 is closed in this state, that is, when it is rotated clockwise in FIGS. 7 to 9, the locking projection 54 of the stay 53 comes into contact with the first protrusion 21 (FIG. 7B). ) State). Here, when the stay 53 is elastically deformed inward so that the locking projection 54 gets over the first locking projection 21, the locking projection 54 is positioned between the two locking projections 21. This state is maintained (the state shown in FIG. 8). 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. (State of FIG. 9).
[0036]
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.
[0037]
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 pressing the opening / closing end of the lid 50, preferably the pressing portions 57 on both sides or the vicinity thereof as shown in FIG. Then, the claw portion 56 a of the locking claw 56 gets over and engages with the bottom peripheral edge portion 22 a of the locking hole 22. At this time, as shown in FIG. 10A, by pushing the upper portion of the lid 50, preferably the pressing portion 57 in the direction of arrow A, the lid 50 rotates in the closing direction while being slightly elastically deformed. The locking claw 56 easily engages with the locking hole 22. On the contrary, as shown in FIG. 10B, when pressed in the direction of the arrow B, the lid 50 rotates in the opening direction while being slightly elastically deformed, so that the engagement of the engagement pawl 56 with the engagement hole 22 is prevented. Canceled. As described above, the lid 50 according to the present embodiment can be easily elastically deformed by pressing in the same direction as the opening / closing operation of the lid 50, and the opening / closing operation can be performed very simply and stably. it can.
[0038]
As described above, the lid 50 of the air cleaning device 1 of the present embodiment can perform operations such as replacement of the charge collecting unit 30 while holding the lid 50 in an open state regardless of how the air cleaning device 1 is placed. At this time, the lid 50 does not close even if the hand is released from the lid 50. In particular, even when the air cleaning device 1 is installed at a high place, there is no need to put in and take out the electrification collecting unit 30 while holding the lid 50 with one hand while taking care of the scaffold.
[0039]
Furthermore, since the cover body 50 is integrally formed of plastic up to the stay part 53, it can be washed. That is, unlike the structure according to the prior art, there is an advantage that it is not necessary to take troubles such as removing a metal connecting member or a magnet for engaging with the stay before cleaning.
[0040]
Here, the lid 50 has a curved shape in order to maximize the area of the suction port in the air purifier that has been made compact. However, because of the curved shape, the lid 50 has a property of being easily elastically deformed. It is used to engage and disengage the holding mechanism when opening and closing. Accordingly, the opening / closing operation is easy and the holding mechanism can be reliably engaged and disengaged. Further, since the holding mechanism is engaged and disengaged using the elastic deformation of the entire lid 50 as described above, the locking claw 56 can be made larger and more robust than the conventional one, and there is a risk of breakage or the like. Absent. In the present embodiment, the suction port 51 of the lid 50 is formed by the rib 59A along the bending direction and the rib 59B perpendicular to the bending direction. However, the shape and size of the rib 59A along the bending direction are the same. It is assumed that it is easily elastically deformed along the bending direction.
[0041]
Further, since the stay portion 53 is integrally provided in the lid 50, the number of parts can be reduced, and the lid 50 can be attached to and detached from the casing 11 while maintaining the function of the conventional stay portion. Work can be performed easily.
[0042]
The air purifying apparatus 1 according to the present embodiment described above can reduce the dead space in the substantially bowl-shaped casing 11 to the maximum to achieve compactness and maximize the suction area for dust-containing air and the like, and the airflow loss. There is an effect that can be reduced.
[0043]
Moreover, the air purification apparatus 1 of embodiment can be stably installed in the empty space of the upper surface 111a of the rocker 111, for example, as shown to Fig.11 (a), or, as shown to FIG.11 (b), leg 1a is attached. It can be put up and put up, and the space can be used effectively. 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.
[0044]
Further, as shown in FIG. 12 (a), the air cleaning device 1 having the legs 1a can be set up on the floor, and as shown in FIG. 12 (b), a flange 1b is attached to one end portion in the width direction to vertically It can also be placed and installed at the corner of the room by attaching the flange 1c only on the front surface as shown in FIG. 12 (c). Can be installed in narrow spaces. Furthermore, as shown in FIG. 13A, 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.13 (a), it can install also upside down.
[0045]
In any of the above-described installation modes, the air cleaning device 1 of the present embodiment can perform the opening / closing operation of the lid 50 as described above.
[0046]
