The tributary to which the active species is supplied merges with the air flow (main flow) indicated by the solid line arrow in FIG. 3 and is sent to the top air outlet 13a side. The active species supplied to the tributary reaches the deodorizing filter 32, and the deodorizing effect in the deodorizing filter 32 is enhanced.

  Hereinafter, the air cleaning chamber 3 of the present invention will be described in detail.

  As shown in FIGS. 4A and 4B, the air cleaning chamber 3 is provided with a filter cover 33, a deodorizing filter frame 35, a dust collection filter 31, and a deodorizing filter 32. The filter cover 33 fixed to the casing 1 a accommodates a dust collection filter 31 and a filter frame 35 disposed above the dust collection filter 31. A deodorizing filter 32 is held inside the filter frame 35.

  As shown in FIG. 3, the dust collection filter 31 and the deodorizing filter 32 are disposed substantially horizontally between the blower chamber 2 and the humidifying chamber 4 on the leeward side of the blower chamber 2 (above the blower chamber 2). Further, the deodorizing filter 32 is disposed on the leeward side with respect to the dust collection filter 31. 3, when the blower fan 20 is driven, air flows from the windward side to the leeward side, that is, from the blower fan 20 toward the humidifying filter 51 from below to above.

  The deodorizing filter 32 has a rectangular shape, and adsorbs or decomposes formaldehyde, odorous components and the like from the passing air. As shown in FIG. 5, the outer periphery of the deodorizing filter 32 is supported by a deodorizing filter frame 35.

  The deodorizing filter frame 35 is a rectangular frame corresponding to the outer shape of the deodorizing filter 32. The deodorizing filter frame 35 includes a plurality of first claw portions 37a formed on the left side wall 36b, second claw portions 37b (see FIG. 9) formed on the right side wall 36c, and lower portions of the front wall 36a and the back wall 36d. And a pressing portion 38 formed on the surface. However, the pressing part 38 is not formed in the lower part of the left side wall 36b. Accordingly, when the deodorizing filter frame 35 is attached to the casing 1a, the deodorizing filter frame 35 rotates with the first claw portion 37a serving as a fulcrum when compared with the case where the pressing portion is formed on the left side wall 36b. It is possible to prevent the pressing portion from interfering (pressing) with the dust collecting filter 31. Moreover, the pressing part is not formed in the right side wall 36c. Thereby, compared with the case where a pressing part is formed in the right side wall 36c, when attaching the deodorizing filter frame 35 to the casing 1a, it is possible to prevent the pressing part from hitting the attachment / detachment opening 15 and becoming difficult to enter. By forming the pressing portion 38 below the front wall 36a and the back wall 36d, the direction in which the dust collecting filter 31 is easily bent can be pressed to prevent bending.

  The first claw portion 37a protrudes outward in the direction orthogonal to the left side wall 36b. The second claw portion 37b protrudes outward in the direction orthogonal to the right side wall 36c. The pressing part 38 protrudes below the lower ends of the left side wall 36b and the right side wall 36c, and the lower edge of the pressing part 38 extends in the horizontal direction. When the deodorizing filter frame 35 is viewed from the left side in the horizontal direction, the lower ends of the pressing portion 38 of the front wall 36a and the pressing portion 38 of the rear wall 36d are lower than the lower ends of the left wall 36b and the right wall 36c. positioned.

  As shown in FIG. 6, the dust collection filter 31 has a rectangular shape, and collects and removes fine dust from the passing air. The dust collection filter 31 is made of a non-woven fabric, and is integrally formed from a base portion 40 and a dust collection portion 41 formed inside the base portion 40.

  The base 40 is a rectangular frame including a front part 40a, a left side part 40b, a right side part 40c, and a back part 40d constituting the outer peripheral part (four sides) of the dust collection filter 31.

  The dust collection portion 41 is a bellows-like filter that is formed by breezing (folding in a mountain or valley) and can expand and contract in a direction (vertical direction) extending from the left side surface portion 40 b to the right side surface portion 40 c of the dust collection filter 31. With this configuration, the dust collection filter 31 is easily bent vertically in the vertical direction as compared to the direction (lateral direction) extending from the front surface portion 40a to the back surface portion 40d. In addition, while the deodorizing filter 32 is supported by the deodorizing filter frame 35, the outer peripheral part of the dust collection filter 31 is not supported by the filter frame.

  As shown in FIG. 7, the filter cover 33 has a box shape in which an upper end and a lower end are opened, and includes a lower support portion 43 and an upper storage portion 44. The upper end surface of the support portion 43 constitutes a part of a seat surface 45 b described later, and supports the dust collection filter 31 accommodated in the accommodation portion 44. The storage unit 44 stores the dust collection filter 31 and the deodorization filter 32. A step portion 45 a is provided between the support portion 43 and the accommodating portion 44, and the seat surface 45 b is exposed inside the filter cover 33 by the step portion 45 a. For this reason, when the filter cover 33 is viewed from above, the outer dimension of the housing part 44 is larger than the outer dimension of the support part 43. When the dust collecting filter 31 is housed in the housing portion 44, the lower end surface of the base 40 constituting the four sides of the dust collecting filter 31 comes into contact with the seating surface 45b.

  The accommodating portion 44 includes a front side standing wall 44a, a left side standing wall 44b, a right side standing wall 44c, and a back side standing wall 44d. A pair of rectangular left holes 47a extending in the horizontal direction are formed in the upper part of the left standing wall 44b. A right hole 47b is formed in the upper part of the right standing wall 44c. When the deodorizing filter frame 35 is housed in the housing portion 44, the first claw portion 37a of the deodorizing filter frame 35 is locked to the left hole 47a, and the second claw portion 37b is locked to the right hole 47b.

  Next, with reference to FIG. 8 and FIG. 9, the state which fixed the dust collection filter 31 and the deodorizing filter 32 to the casing 1a via the accommodating part 44 is demonstrated. FIG. 8 shows a cross section of the blower chamber 2 and the air cleaning chamber 3 taken along line AA of FIG. FIG. 9 shows a cross section of the blower chamber 2 and the air cleaning chamber 3 taken along line BB in FIG.

  As shown in FIG. 8, the blower fan 20, the dust collection filter 31, and the deodorizing filter 32 are sequentially disposed in the casing 1 a from the lower side to the upper side, that is, from the windward side to the leeward side.

  In the dust collection filter 31 disposed between the blower fan 20 and the deodorizing filter 32, the lower end surface of the base portion 40 abuts on the seat surface 45 b to form the seal portion 6. The seal portion 6 is located on the windward side (lower side) of the dust collection filter 31 and seals between the dust collection filter 31 and the blower chamber 2. Since the seal portion 6 is positioned on the leeward side of the dust collection filter 31, the dust collection filter 31 is configured to be attachable and detachable from the leeward side of the seal portion 6.

  As shown in FIG. 9, the deodorizing filter frame 35 disposed on the leeward side (upper side) of the dust collecting filter 31 has a first claw portion 37a locked in the left hole 47a (see FIG. 7), and a second claw. The portion 37 b is locked in the right hole 47 b and fixed in the housing portion 44. At this time, the lower end surface of the pressing portion 38 formed on the front wall 36a of the deodorizing filter frame 35 presses the upper end surface of the front portion 40a formed on the dust collection filter 31 downward with a force F1 ( (See FIG. 8). Similarly, the lower end surface of the pressing portion 38 formed on the back wall 36d of the deodorizing filter frame 35 presses the upper end surface of the back surface portion 40d formed on the dust collection filter 31 downward with a force F1. That is, the deodorizing filter frame 35 presses two opposing sides along the vertical direction of the dust collection filter 31 from the leeward side toward the leeward side. A gap L is formed between the left side wall 36b of the deodorizing filter frame 35 and the left side surface portion 40b of the dust collection filter 31, and between the right side wall 36c of the deodorization filter frame 35 and the right side surface portion 40c of the dust collection filter 31. It is formed (see FIG. 9).

  From the above, as shown by the arrow C in FIG. 8, when the blower fan 20 is driven, the air flows from the windward to the leeward, and the deodorizing filter frame 35 is disposed in the direction opposite to the air flow direction. 31 is pressed with force F1. Further, when the dust collection filter 31 is pressed by the deodorizing filter frame 35, the lower end surface of the base 40 of the dust collection filter 31 presses the seat surface 45b with a force F2 from the leeward side toward the windward side.

  Hereinafter, the procedure for attaching the dust collection filter 31 and the deodorizing filter 32 to the casing 1a will be described with reference to FIG.

  In order to house the dust collection filter 31 and the deodorizing filter 32 in the housing part 44 fixed to the casing 1a, as shown in FIG. 10 (a), the dust collection filter 31 is removed from the desorption port 15 above the seat surface 45b. Insert into the housing 44. Then, the dust collection filter 31 is positioned by the seat surface 45b (see FIG. 10B). That is, the dust collection filter 31 is attached from the leeward side of the seal portion 6.

  Thereafter, the deodorizing filter frame 35 supporting the deodorizing filter 32 is inserted into the accommodating portion 44 through the desorption port 15. The deodorization filter 32 is lowered from above the dust collection filter 31 in parallel with the air flow direction. First, the first claw portion 37a of the deodorization filter frame 35 is engaged with the left hole 47a of the filter cover 33 to collect the dust. The filter 31 is inclined. Thereafter, the deodorizing filter frame 35 rotates around the first claw portion 37 a as a fulcrum, and the deodorizing filter 32 is in a state parallel to the dust collection filter 31. In this way, the deodorizing filter 32 is attached so as to be stacked on the dust collection filter 31 (see FIG. 10C). At this time, the second claw portion 37 b of the deodorizing filter frame 35 is engaged with the right hole 47 b of the filter cover 33. Thereby, attachment of the dust collection filter 31 and the deodorizing filter 32 is completed.

  It is assumed that the dust collection filter 31 and the deodorizing filter 32 need to be taken out again for maintenance and the like. At this time, first, the humidifying unit 50 is removed, and then the deodorizing filter frame 35 and the dust collecting filter 31 are sequentially taken out from the desorption port 15. That is, the dust collection filter 31 is taken out from the leeward side from the seal portion 6.

Moreover, when attaching the deodorizing filter 32, since the dust collection filter 31 can be visually recognized and attached from upper direction, the attachment property of the deodorizing filter 32 can be improved.

  In the air cleaner 1 of the present embodiment, since there is no pressing portion on the lower side in the oblique direction to which the deodorizing filter frame 35 is attached, when the deodorizing filter frame 35 is attached, interference between the pressing portion and the dust collection filter 31 is prevented. Wearability can be improved.

  As mentioned above, although embodiment of this invention was described based on drawing, it should be thought that a specific structure is not limited to these embodiment. The scope of the present invention is shown not only by the above description of the embodiments but also by the scope of claims for patent, and further includes all modifications within the meaning and scope equivalent to the scope of claims for patent.

  In the first embodiment, the dust collection filter 31 is configured to be easily bent up and down in the vertical direction, but may be easily bent up and down in the horizontal direction. At this time, the deodorizing filter frame 35 is configured to press the left side surface portion 40b and the right side surface portion 40c of the dust collection filter 31.

  In the first embodiment, only the deodorizing filter 32 is attached to the deodorizing filter frame 35. However, as shown in FIG. 11, a specialized filter 34 may be additionally attached above the deodorizing filter 32. The specialized filter 34 is, for example, an adsorption filter with improved ammonia adsorption characteristics, and is used specifically for a use scene such as a toilet.

  In the first embodiment, the deodorizing filter 32 is attached so as to be stacked on the dust collecting filter 31 from above the dust collecting filter 31. However, the present invention is not limited to this, and the deodorizing filter 32 may be attached so as to be stacked on the dust collecting filter 31 from the side of the dust collecting filter 31.

  Although the air cleaner 60 of 2nd Embodiment shown in FIG. 12 is provided with the ventilation chamber 2 and the air purification chamber 3, it differs from the air cleaner 1 of 1st Embodiment by the point which is not provided with the humidification chamber 4. FIG. In this air purifier 60, the air taken in by driving the blower fan 20 passes through the dust collection filter 31 and the deodorizing filter 32, and is then discharged into the room from the top air outlet 13a. In addition, the same code | symbol is attached | subjected to the same element as the air cleaner 1 of 1st Embodiment, and description is abbreviate | omitted.

  A desorption port 62 for attaching and removing the dust collection filter 31 and the deodorizing filter 32 is formed on the upper portion of the front panel 61 of the air cleaner 60. In order to attach the dust collection filter 31 to the air cleaner 60, the dust collection filter 31 is inserted into the air cleaner 60 from the desorption port 62 as shown in FIG. The dust collecting filter 31 is positioned with its lower end surface in contact with the seating surface 45b, and forms a seal portion 6 between the dust collecting filter 31 and the seating surface 45b.

  Thereafter, the deodorizing filter 32 (deodorizing filter frame 35) is slid from the side of the dust collection filter 31 at a height H1 as shown in FIG. Here, sliding the deodorization filter 32 from the side of the dust collection filter 31 means that the deodorization filter 32 is slid in parallel with a large area of the dust collection filter 31. That is, the side of the dust collection filter 31 refers to a position where the deodorizing filter 32 can be attached or removed in parallel to a surface having a large area of the dust collection filter 31. Therefore, the sliding direction of the deodorizing filter 31 is orthogonal to the air flow direction. The deodorizing filter frame 35 has a rectangular shape, and pressing portions are formed on two sides along the sliding direction, and pressing portions are not formed on the two sides on the far side and the near side in the sliding direction.

  Then, the deodorizing filter frame 35 is guided obliquely downward by the guide 63, and is disposed so as to be pushed up to the height H2 and stacked on the dust collection filter 31 (see FIG. 12C). When the deodorizing filter frame 35 is pushed downward, the deodorizing filter frame 35 presses the dust collection filter 31 downward. Therefore, the space between the lower end surface of the peripheral edge of the dust collection filter 31 and the seating surface 45b is reliably sealed. The heights H1 and H2 indicate the lower end position of the deodorizing filter frame 35, and the height H2 when the deodorizing filter frame 35 is completely attached is higher than the height H1 when the deodorizing filter frame 35 is slid. Located below. As described above, the deodorizing filter 32 can be easily attached by sliding from the side.

  Further, since there is no pressing portion on the back side in the mounting direction of the deodorizing filter frame 35, when the deodorizing filter frame 35 is slid and mounted, the interference between the pressing portion and the dust collecting filter 31 is prevented and the mounting property is improved. it can.

  When removing the deodorizing filter 32, the deodorizing filter frame 35 is pulled from the desorption port 62 and slid sideways. Similarly, the dust collection filter 31 is pulled from the desorption port 62 and is slid sideways to be taken out from the air cleaner 60.

  In addition, although the vertical type air cleaner 1 was employ | adopted in the said embodiment, it is not limited to this, For example, you may employ | adopt other air purifiers, such as a horizontal type. In the vertical air cleaner 1, air flows upward from below, whereas in the horizontal air cleaner, air flows in the horizontal direction. Furthermore, in a horizontal air cleaner, for example, a large-area surface of a dust collection filter or a deodorizing filter is arranged so as to be orthogonal to the air flow direction. At this time, the deodorizing filter is moved and attached to the side of the dust collection filter, that is, in a direction orthogonal to the air flow direction.
