Problems solved by technology

[0004] However, the second filter has coarser and softer pores than the first filter, so it tends to wrinkle
After attaching the pleat-shaped first filter to the first frame and then adhering the second filter to the first frame, if the second filter is wrinkled, it will become a defective product and cannot be used as a product
That is, not only the second filter, but also the first filter cannot be used as a product

no. 1 Embodiment approach

[0021] Next, a first embodiment of the present invention will be described using the drawings.

[0022] figure 1 It is a cross-sectional view of the air cleaner according to the first embodiment of the present invention. Such as figure 1 As shown, the air cleaner of this embodiment is provided with an air blower 2 and an air filter 3 inside the main body case 1 .

[0023] The main body case has a substantially elongated box shape, and an air inlet 4 is provided on the front side of the main body case, and an exhaust port 5 is provided on the top surface of the main body case. A wind direction louver 6 is provided at the air outlet 5 .

[0024] The air blower 2 is arranged in the air path between the air inlet 4 and the air outlet 5 of the main body casing 1, and a casing 7 in the shape of a volute acts as a centrifugal blower arranged in the casing 7. Blades 8 of the fan and a motor (not shown) that rotates the blades 8 are formed.

[0025] In addition, the air filter 3 i...

no. 2 Embodiment approach

[0045] Figure 6 It is an exploded perspective view of the second filter of the air filter of the air cleaner of the second embodiment of the present invention. also, Figure 6 It is a figure seen from the downstream side of the blowing direction. Figure 7 It is an exploded perspective view of the air filter of the air cleaning device of the second embodiment of the present invention. also, Figure 7 It is a figure seen from the upstream side of the blowing direction. The same reference numerals are assigned to the same components as those in the first embodiment, and detailed description thereof will be omitted.

[0046] The second embodiment differs from the first embodiment in that the structure of the second filter 12 and that the second filter 12 can be freely attached to and detached from the second frame 11 .

[0047] Such as Figure 6 As shown, the second filter 12 may be integrally bonded with an additional filter 20 in addition to the pre-filter unit 16 on the d...

no. 3 Embodiment approach

[0056] Figure 8 It is a perspective view of the second filter 12 of the air filter of the air cleaner of the third embodiment of the present invention. also, Figure 8 It is a figure seen from the downstream side of the blowing direction. The same reference numerals are assigned to the same components as those in the first embodiment, and detailed description thereof will be omitted.

[0057] The third embodiment differs from the first embodiment in the wrinkle suppressing portion. Specifically, the pre-filter portion 16 of the second filter 12 is made of resin, and the wrinkle suppressing portion 13 of the second filter 12 is formed by filling at least a part of holes in the peripheral portion of the pre-filter portion 16 with thermal fusion. Specifically, the peripheral portion of the pre-filter 16 is sandwiched between high-temperature metals, and the peripheral portion of the pre-filter 16 is melted by heat to fill the holes, thereby forming the peripheral portion of t...

Abstract

The air cleaning device comprises a first filter (9) in a folding shape, a first frame (10) keeping the shape of the fist filter (9), a second frame (11) fixed at the first frame (10), and a second filter (12) arranged at the surface of one side of the first filter (9). The second filter (12) includes a wrinkling restriction part (13) configured to restrict the wrinkling of the second filter (12), and installed at the second frame (11) to further reduce the poor technology of the air filter. The second filter is able to be taken as different parts of the wrinkling restriction part (13) for restricting the wrinkling of the second filter (12) to manufacture, so that the structure of an air filter is stable and is not easy to have good conditions at work.

Description

technical field [0001] The present invention relates to an air filter incorporated in an air conditioner or the like, and an air cleaning device equipped with the air filter. Background technique [0002] Existing air filters, such as Japanese Patent Application Laid-Open No. 01-180213, have a first filter in the shape of pleats, a first frame for maintaining the shape of the first filter, and a frame mounted on the first filter. The second filter on one surface side is fixed to the first frame. [0003] In the process of producing the air filter, the pleat-shaped first filter and the second filter are sequentially bonded and fixed on the first frame. [0004] However, the second filter has thicker and softer pores than the first filter, so it tends to wrinkle. After attaching the pleat-shaped first filter to the first frame, and then bonding the second filter to the first frame, if the second filter is wrinkled, it becomes a defective product and cannot be used as a produ...
