Description

  The present invention relates to an air cleaner, and more particularly to an air cleaner having a humidifying function.

  Conventionally, as an air cleaner provided with a humidification function, for example, the one described in Patent Document 1 is known. The air purifier described in Patent Document 1 includes an air purifying filter in the order from the upstream side (suction port side) to the downstream side (blower port side) in the flow of air inside the main body housing having the suction port and the air outlet. A unit (dust collection unit or deodorizing unit), a vaporizing filter (humidification unit) for humidifying air, and a blower fan are arranged. The vaporization filter is disposed so as to overlap a part of the lower side of the air purification filter unit.

  As described above, since the vaporization filter is arranged so as to overlap a part of the air purification filter unit, a part of the air taken into the main body housing from the suction port by the rotation of the blower fan is air purification. The dust passes through only the filter unit and is removed, and the remaining part passes through the air purification filter unit and the vaporization filter in this order to be removed and humidified. Then, the dust-only air and the dust-removed / humidified air are blown out of the main body housing from the outlet through the rotation of the blower fan.

  However, in the air cleaner described in Patent Document 1, the ventilation resistance of the air flow path that passes through both the air purification filter unit and the vaporization filter is more than the ventilation resistance of the air flow path that passes through only the air purification filter unit. growing. Accordingly, the amount of air flowing through the air flow path having a large ventilation resistance, that is, the amount of air passing through both the air purification filter unit and the vaporization filter is reduced, so that the amount of air passing through the vaporization filter is reduced and the amount of humidification of the air There was a problem that decreased.

When performing maintenance of the humidifying unit 24 such as cleaning or replacement, the door 17 is opened and closed so that the water supply tank can be replenished with water or the humidifying unit 24 can be attached or detached.

  The blower 25 includes a turbo fan 25a and a fan motor 25b. The turbo fan 25a is made of a synthetic resin material and is connected to the output shaft of the fan motor 25b. The fan motor 25b has a variable number of rotations, and the turbo fan 25a also rotates as the fan motor 25b rotates, and air flows into the air purifier 1 from the air suction ports 13a to 13d by the rotation of the turbo fan 25a. Then, air flows out from the inside of the air cleaner 1 through the air outlets 14a to 14c.

  As shown in FIGS. 3 and 5, the blocking member 30 is disposed on the downstream side of the deodorizing filter 23 a of the deodorizing unit 23 and on the upper left side of the humidifying unit 24. FIG. 5 is a perspective view of an external appearance of a main part of the air cleaner 1 as viewed from the right rear obliquely, and the rear panel 14 and the blower 25 are not shown for explanation.

  As shown in FIG. 4, the blocking member 30 is made of a synthetic resin material, and includes a support portion 31, a first connecting portion 32, a second connecting portion 33, a third connecting portion 34, and a shielding portion 35. Have. As shown in FIG. 4B, the support portion 31 is formed in a plate shape that is substantially L-shaped when viewed from the direction of arrow D. When the blocking member 30 is attached to the air purifier 1, the support portion 31 is fixed to an attachment portion (not shown) of the reinforcing member 23 cb and the holding portion 23 c as shown in FIG. The arrangement is substantially orthogonal.

  The first connecting portion 32 is formed in a plate shape that is a horizontally long rectangular shape. As shown in FIG. 4B, the length in the horizontal direction is shorter than the length in the horizontal direction of the support portion 31. Yes. As shown in FIGS. 4A and 4B, the first connecting portion 32 is formed so as to extend slightly from the lower side to the upstream side from the fixing position of the support portion 31 to the reinforcing member 23cb. The right end of the connecting portion 32 is formed so as to be aligned with the right end of the support portion 31. The length of the first connecting portion 32 in the front-rear direction will be described later when the shielding portion 35 is described.

  As shown in FIGS. 5 and 7B, the second connecting portion 33 has an arc shape having a radius of curvature that is slightly larger than the radial dimension of the opening 23ca of the holding portion 23c. As shown in FIGS. 4B and 4C, the second connecting portion 33 is formed so as to extend upstream from the support portion 31. Further, as shown in FIGS. 4A and 4B, the upper end of the second connecting portion 33 is connected to the left end of the first connecting portion 32. The length of the second connecting portion 33 in the front-rear direction is the same as the length of the first connecting portion 32 in the front-rear direction.

  The 3rd connection part 34 is formed in the plate shape used as a horizontally long rectangular shape, and as shown in FIG.4 (B), the length of a horizontal direction is the length of the horizontal direction of the support part 31, and a 1st connection part. It is formed to be shorter than 32 lateral lengths. As shown in FIGS. 4A and 4B, the third connecting portion 34 is formed so as to extend upstream from the lower end of the support portion 31, so that the left end is aligned with the left end of the support portion 31. Is formed. Further, as shown in FIGS. 4B and 4C, the right end of the third connecting portion 34 is connected slightly above the lower end of the second connecting portion 33. By arranging the third connecting portion 34 on the support portion 31 as described above, the third connecting portion 34 serves as a reinforcing material that prevents the support portion 31 and the shielding portion 35 from being deformed. The length of the third connecting portion 34 in the front-rear direction is the same as the length of the first connecting portion 32 in the front-rear direction.

  The shielding part 35 is formed in a plate shape, and is supported by the support part 31 by the first connecting part 32, the second connecting part 33, and the third connecting part 34, as shown in FIG. When the support portion 31 is fixed to a mounting portion (not shown) of the reinforcing member 23cb and the holding portion 23c, the shielding portion 35 is disposed so as to be substantially orthogonal to the air flow in the ventilation path 10. The length of the first connecting part 32, the second connecting part 33, and the third connecting part 34 in the front-rear direction is such that the shielding part 35 is not in contact with the outer peripheral surface of the humidifying filter 24a when the distance between the shielding part 35 and the humidifying filter 24a is reached. It is determined so that the arrangement becomes a distance close to each other. Moreover, the lower end part of the shielding part 35 is made into the circular arc shape according to the shape of the outer peripheral surface of the humidification filter 24a, as shown in FIG.5, FIG.6 (B) and FIG.7 (B), and reinforcement member 23cb When the support part 31 is fixed to the upstream side, the upstream side of the frame body 24c of the humidifying filter 24a is formed so as to cover approximately one-eighth.

  Next, using FIGS. 3 to 7, the operation of each component and the air flow when the air cleaner 1 having the above-described configuration is operated will be described, and the effect of the blocking member 30 will be achieved. Will be described. Here, FIG. 6 is an enlarged view of the cross section QQ in FIG. 5, (A) shows the air flow (arrows F1, F2) when the blocking member 30 is not provided, and (B) is the blocking. The flow of air when the member 30 is provided (arrows F1, F3, F4) is shown. 7 is an enlarged view of the section RR in FIG. 5, (A) shows the air flow (arrows F5 and F6) when the blocking member 30 is not provided, and (B) is the blocking member. The air flow (arrow F5, F7, F8) at the time of providing 30 is shown. In FIGS. 6 and 7, drawing of components other than those necessary for explaining how the blocking member 30 acts on the air flow is omitted.

  When the air cleaner 1 starts operation, the blower 25 is driven and energization of the first electric dust collector 22a and the second electric dust collector 22b of the dust collecting unit 22 is started. Further, when air is humidified together with air purification, the humidification filter 24a of the humidification unit 24 starts rotating. When the blower 25 is driven, air is sucked into the ventilation path 10 from the air suction ports 13a to 13d of the top surface suction port 13a, the right side surface suction port 13b, the left side surface suction port 13c, and the bottom surface suction port 13d.

  The air sucked into the ventilation path 10 flows toward the downstream side (blower 25 side) through the following three air paths. The first air path is a path that passes through a place where the lower part of the deodorizing unit 23 and the upper part of the humidifying unit 24 are overlapped in the front-rear direction (drawn as a middle stage path M in FIG. In the middle path M, air passes in the order of the pre-filter 21 → the dust collecting unit 22 → the deodorizing unit 23 → the humidifying unit 24. The second air path is a path that passes above the humidifying unit 24 among places where the deodorizing unit 23 and the humidifying unit 24 do not overlap in the front-rear direction (drawn as an upper path U in FIG. 6. In the upper path U, air passes through the prefilter 21 → the dust collecting unit 22 → the deodorizing unit 23 in this order. The third air path is a path that passes below the deodorizing unit 23 among the places where the deodorizing unit 23 and the humidifying unit 24 do not overlap in the front-rear direction (drawn as a lower path L in FIG. 6. In the lower path L, air passes in the order of the prefilter 21 → the dust collecting unit 22 → the humidifying unit 24.

  When air flows through the ventilation path 10 through the above-described paths, the prefilter 21 and the energized dust collection unit 22 remove dust and pollen contained in the sucked air. Moreover, in the deodorizing unit 23, the odor component contained in the inhaled air is removed. Further, the humidified unit 24 humidifies the sucked air. The air that has been dedusted, deodorized, and humidified when flowing through the ventilation path 10 is supplied to the air cleaner 1 from the air outlets of the upper surface outlet 14a, the right side outlet 14b, and the left side outlet 14c by driving the blower 25. It is blown out.

  Next, the flow of air in the ventilation path 10 when the blocking member 30 is provided in the ventilation path 10 will be described.

  As described above with reference to FIGS. 3 and 5, the blocking member 30 is attached to the reinforcing member 23 cb so that it is downstream of the deodorizing filter 23 a of the deodorizing unit 23 and above the humidifying unit 24. Be placed. That is, the blocking member 30 is arranged in the upper path U among the three air paths described above. Since the blocking member 30 is arranged in the upper path U in this way, a part of the air flowing through the deodorizing unit 23 toward the downstream side out of the air flowing through the upper path U is shielded 35 of the blocking member 30. The flow is interrupted by.

  In the following, using FIG. 6 and FIG. 7, a part of the air passing through the deodorizing unit 23 toward the downstream side is blocked by the shielding portion 35 of the blocking member 30, and as a result, the amount of air flowing to the humidifying unit 24 increases. This will be described in detail.

  6 (A) and 7 (A) show the air flow when the blocking member 30 is not provided in the ventilation path 10, and in FIG. 6 (A), the air flowing through the middle path M is shown. The air flowing through the upper path U is indicated by an arrow F1, and the air flowing through the upper path U is indicated by an arrow F2. Further, in FIG. 7A, the air flowing in the vicinity of the central portion in the left-right direction, that is, the place where the deodorizing filter 23a and the humidifying filter 24a are overlapped is indicated by an arrow F5, and only the deodorizing filter 23a passes through the heating filter 24a. The air flowing on the left side of the frame 24c is indicated by an arrow F6. Here, the air F2 flowing through the upper path U and the air F6 in FIG. 7A, that is, the amount of air passing through only the deodorizing filter 23a, is the center of the deodorizing filter 24a (the humidifying filter 24a has a disk shape). The amount of air humidified by the humidifying filter 24a decreases from the center to the left side (indicated as C / L in FIG. 7).

  On the other hand, as shown in FIG. 6B and FIG. 7B, when the blocking member 30 is provided in the ventilation path 10, the shielding portion 35 of the blocking member 30 causes the blocking member 30 in FIG. The air flow F2 and the air flow F6 in FIG. Thereby, while the amount of air passing through only the deodorizing filter 23a is reduced, the air flow F3 shown in FIG. 6B and the air flow F7 shown in FIG. 7B are generated, and the deodorizing filter 23a and the humidifying filter 24a are generated. The amount of air passing through both increases. It should be noted that, instead of the air flow F2 blocked by the shielding part 35 shown in FIG. 6 (A), a slight amount of the deodorizing filter 23a and the shielding part 35 are shown as in the air flow F4 shown in FIG. 6 (B). It flows to the humidification filter 24a through the space between. Similarly, in place of the air flow F6 blocked by the shielding portion 35 shown in FIG. 6A, the deodorizing filter 23a and the shielding portion 35 are slightly changed like the air flow F8 shown in FIG. 7B. It flows to the humidification filter 24a through the space between. Therefore, the air flowing in the air flows F4 and F8 also contributes to an increase in the amount of air humidified by the humidifying filter 24.

  As described above, the second connecting portion 33 has an arc shape having a radius of curvature that is slightly larger than the radial dimension of the opening 23ca. Thereby, only the deodorizing filter 23a by the shielding part 35 and the flow of the air which flows downstream are blocked | interrupted more reliably. Further, the lower end portion of the shielding portion 35 is disposed so as to cover the upstream side of the frame body 24 c of the humidifying unit 24. Also by this, the flow of the air which passes only the deodorizing filter 23a and flows to the downstream side by the shielding part 35 is interrupted more reliably. As a result, the amount of air passing through the humidifying filter 24a further increases.

  As described above, by disposing the blocking member 30 in the upper path U in the ventilation path 10, the deodorization is performed as in the air flow F2 in FIG. 6 (A) and the air flow F6 in FIG. 7 (A). The amount of air flowing in the air flows F3 and F4 in FIG. 6B and the air flows F7 and F8 in FIG. 7B is blocked while only the filter 23a passes through the humidifying filter 24a. Will increase. Thereby, the air quantity which passes the humidification filter 24a can be increased, and sufficient humidification quantity can be obtained.

  Furthermore, since the blocking member 30 is disposed downstream of the deodorizing filter 23a of the deodorizing unit 23, as described above, above the humidifying unit 24 and on the left side of the target central axis in the left-right direction of the humidifying filter 24a. Even when the shielding portion 35 is formed large (for example, in a size that covers the upstream side of the frame 24c of the humidifying filter 24a by approximately two-eighths), the humidifying unit 24 can be attached to and detached from the main body portion 11 for maintenance or the like. Without obstructing, the door 17 can be opened and the humidifying unit 24 can be easily put in and out of the door 17.

  In the embodiment described above, the case where the air cleaning unit is a deodorizing unit has been described. However, the present invention is not limited to this, and the air cleaning unit is a dust collection unit arranged on the upstream side of the humidification unit. Also good.
