It is a thing. The second outer frame portion 31 is slightly larger than the first outer frame portion 21 of the first frame body 19 and can accommodate the first frame body 19 with almost no gap inside. The short side wall 33 of the second outer frame is formed with a locking hole 34 at which the locking projection 24 of the first frame 19 can be engaged and disengaged at three positions, both ends and the center. In addition, the long side wall 35 of the second frame 20 is formed with locking holes 34 at four equal parts including both ends. Accordingly, when the first frame body 19 is inserted into the second frame body 20, the locking projection 24 is locked in the locking hole 34, and the both are integrated.

  The second support portion 32 includes a pair of third support beams 36 and a fourth support beam 37 that connect the upper ends of the short sides, and a fifth support beam 38 that connects the center portions of the upper ends of the long side walls 25. ing. Projections 39 are formed at four locations on the lower surface of the fifth support beam 38. These protrusions 39 pierce a second filter 41 described later, and position the second filter 41 with respect to the second frame body 20.

  As shown in FIG. 4, the filter 17 includes a first filter 40 disposed on the upstream side (first filter member 14) of the air flow, and a second filter 41 disposed on the downstream side.

  The first filter 40 includes two filter units 42, and both are the same size. In the state where the first filter 40 is disposed in the frame body 16, the thin plate portion 29 of the first support beam 27 of the first frame body 19 is positioned between the filter portions 42 arranged side by side. When viewed from below, the boundary line BL1 is completely covered by the first support beam 27. The first filter 40 is mainly of a type that deodorizes acetaldehyde, but acetic acid can also be deodorized.

  The second filter 41 includes a main filter portion 43 and a sub filter portion 44, and the main filter portion 43 has a surface area approximately three times that of the sub filter portion 44. In the state where the second filter 41 is disposed in the frame body 16, when viewed from above in FIG. 4, the boundary line BL <b> 2 between the main filter portion 43 and the sub filter portion 44 provided side by side is formed by the third support beam 36. Fully covered. The main filter unit 43 is mainly of a type that deodorizes ammonia, and the sub filter unit 44 is of a type that mainly deodorizes acetic acid.

  Thus, by comprising the 1st filter 40 and the 2nd filter 41 by two filter parts 42, 42, and 43, 44, the fall of intensity can be prevented compared with the case where it constitutes by one sheet. it can. Further, even when the size of the filter 17 is large, it can be manufactured by configuring with a plurality of filter portions 42, 43, 44.

  The spacer 18 has three elongated plate shapes, and is obtained by molding a synthetic resin material. As shown in FIG. 7, each spacer 18 has a wide portion 45 at both ends, and a locking portion 46 is provided at the center of the tip. These locking portions 46 are engaged with and disengaged from the locking holes 26 of the first frame body 19. A plurality of first protrusions 47 are formed on the upper surface of each spacer 18, and a plurality of second protrusions 48 are formed on the lower surface. Two first protrusions 47 are provided on both ends of the spacer 18. The second protrusion 48 is provided with a position shifted from the first protrusion 47 in the longitudinal direction of the spacer 18. The first protrusion 47 pierces the first filter 40, and the second protrusion 48 pierces the second filter 41. In the portion where the protrusion 30 is pierced, the thickness of the filter 17 slightly increases on the surface opposite to the piercing position. Here, since the positions of the first protrusion 47 and the second protrusion 48 are shifted, the thickness of the filter 17 does not partially increase excessively.

The 2nd filter member 15 which consists of the said structure can be assembled as follows.
That is, the first filter 40 is disposed in the first frame body 19. At this time, the thin plate portion 29 of the first support beam 27 enters between the filter portions 42, and the boundary line BL 1 between the filter portions 42 is covered by the first support beam 27. Further, a projection 39 formed on the first support beam 27 of the first frame body 19 is pierced on the lower surface of the first filter 40, and the first filter 40 is positioned with respect to the first frame body 19.

  Then, the three spacers 18 are respectively attached to the first frame body 19. Each spacer 18 is attached by sequentially engaging the locking portions 46 at both ends with the locking holes 26 of the first frame. In a state where the spacer 18 is attached, the second protrusion 48 pierces the first filter 40, and the first filter 40 is also positioned by the spacer 18.

  Subsequently, the second filter 41 is disposed in the first frame body 19. The second filter 41 is arranged such that the boundary line BL1 between the main filter unit 43 and the sub filter unit 44 is aligned with the boundary line BL1 of the first filter 40 attached earlier. At this time, the first protrusion 47 of the spacer 18 previously attached pierces the lower surface of the second filter 41, and the second filter 41 is positioned with respect to the first frame body 19.

  Finally, the second frame 20 is attached to the first frame 19. The mounting operation of the second frame 20 is completed by locking the locking projection 24 of the first frame 19 in the locking hole 34. In this state, the protrusion 39 of the second frame 20 is pierced on the upper surface of the second filter 41 attached in advance, and the second filter 41 is positioned by the spacer 18 and the second frame 20. The boundary line BL <b> 2 between the main filter portion 43 and the sub filter portion 44 of the second filter 41 is covered by the third support beam 36 of the second frame body 20.

  As described above, the second filter member 15 is assembled to the first frame 19 in the order of the first filter 40, the spacer 18, the second filter 41, and the second frame 20 from the same direction. Can be assembled. Therefore, the assembly workability is excellent. Further, the assembled second filter member 15 has the first filter 40 and the second filter 41 positioned by the projections 30, 39, 47, and 48, so that the second filter member 15 is not displaced in use and no abnormal noise is generated. . Further, since the gap can be surely formed by the spacer 18 between the first filter 40 and the second filter 41, the first filter 40 and the second filter 41 pass as in the case of being provided in close contact with each other. Air pressure loss can be suppressed. Furthermore, the boundary line BL1 between the filter parts 42 of the first filter 40 and the boundary line BL2 between the main filter part 43 and the sub filter part 44 of the second filter 41 overlap each other when viewed from the direction in which air passes. Don't be. For this reason, the air passing through the second filter member 15 passes through at least one of the first filter 40 and the second filter 41.

  In addition, this invention is not limited to the structure described in the said embodiment, A various change is possible.

  In the embodiment, the spacer 18 which is a member different from the frame body 16 is provided. However, the spacer 18 can also be provided integrally with the frame body 16. For example, as shown in FIG. 8, if the frame 16 is configured to have the support portion 18 at a position that bisects in the thickness direction, and the first filter 40 and the second filter 41 are assembled from both sides, the separate bodies are provided. The spacer 18 becomes unnecessary. In this case, a separate frame (not shown) is required on both sides in the thickness direction.

  In the embodiment, the second filter member 15 is configured by the first filter 40 and the second filter 41, but may be configured by three or more filters 17. Each filter 17 is configured by two filter units 42, 42 and 43, 44. However, it can be configured by three or more filter units.

  In the above-described embodiment, the filter member employed in the air purifier has been described as an example of the air conditioner. However, the filter member having the above-described configuration can be applied to other types of air conditioners such as a dehumidifier, a clothes dryer, and a blower. Can be adopted.

  In the said embodiment, although the filter was comprised with two of the 1st filter 40 and the 2nd filter 41, it is also possible to set it as 3 or more. In this case, it is preferable that at least one filter is different (two or more filters may be the same type). Moreover, it is necessary to interpose the spacer 18 between each filter.

  In the above-described embodiment, the first filter 40 and the second filter 41 are configured by different types of filters, but these may be the same type, and the same applies to the case of three or more filters.

  In the embodiment, the three spacers 18 are arranged between the first filter 40 and the second filter 41. However, the number is not limited to this, and may be 1, 2 or 4 or more. Further, the positions where these spacers 18 are arranged can be freely set as required.
