Wherein, a can be 0.4mm, 0.6mm or 0.8mm, and can be specifically selected according to the configuration and the internal layout of the shell 1 of the indoor unit of the air conditioner, and is not specifically limited herein as long as the a is within a set range. Therefore, the problem that the flexible filter screen 5 is not smooth in movement due to the fact that the limiting space is too small can be prevented, and the problem that the filter screen 5 is separated from the rotating shaft 6 or stacked due to the fact that the limiting space is too large can be avoided.

Optionally, the indoor unit of the air conditioner further includes a first dust box 91 and a second dust box 92. The first dust collecting box 91 and the second dust collecting box 92 are both clamped on the housing 1 between the first tuyere 11 and the second tuyere 12. The first dust box 91 is provided with a first brushing mechanism 10, and the second dust box 92 is provided with a second brushing mechanism 10. When the filter screen 5 is moved from the first air port 11 to the second air port 12, the first brushing mechanism 10 cleans dust accumulated on the filter screen 5 at the side of the first air port 11 into the first dust collecting box 91; during the movement of the filter screen 5 from the second air opening 12 to the first air opening 11, the second brushing mechanism 10 sweeps the dust accumulated on the filter screen 5 at the side of the second air opening 12 to the second dust collecting box 92. When the air conditioner indoor unit is used for reversing and switching different air openings, dust on the filter screen 5 can be automatically cleaned and collected, and the problem that a filter mechanism of the existing reversing air supply air conditioner indoor unit cannot be automatically cleaned is solved.

Optionally, the grooming mechanism 10 comprises a brush bar 101 and a brush 102. The brush bar 101 is fixed in the first dust box 91 and/or the second dust box 92; the brush 102 is positioned at the upper portion of the brush bar 101, and the brush 102 is in contact with the filter net 5 in the filter net frame assembly 2.

Thus, the brush 102 can penetrate through the first frame 3 to brush and clean the moving filter screen 5 without occupying extra space.

Optionally, the rotating shaft 6 includes a first rotating shaft 6 and a second rotating shaft 6, and the first rotating shaft 6 and the second rotating shaft 6 are fixed on the first frame 3 in a limiting manner through a limiting lock catch. The first rotating shaft 6 and the second rotating shaft 6 are both located and limited in the limiting space and are parallel to the width direction of the indoor unit of the air conditioner. The guide rail 51 on the filter screen 5 is perpendicular to the first rotating shaft 6 and the second rotating shaft 6 and is in transmission connection with the two rotating shafts 6. Through the synchronous equidirectional rotation of two pivot 6, can make the more steady operation of flexible filter screen 5.

Preferably, the number of the rotating shafts 6 is four, two rotating shafts 6 are arranged in parallel above the arc-shaped portion 33 in a straight line shape, and adjacent rotating shafts 6 are connected in a limiting manner through the limiting piece 8. The two filter screens 5 are in one-to-one corresponding meshing transmission with the two rotating shafts 6. The other two rotating shafts 6 are arranged on the upper portion of the bottom plate 14 in a straight line shape in parallel, in a limiting space enclosed by the first frame 3 and the second frame 4, the two adjacent rotating shafts 6 are in limiting connection through the limiting piece 8 and are in meshing transmission with the filter screen 5. By arranging the double-row rotating shaft 6, the filter screen 5 with longer length can slide more stably. The number of the driving devices 7 is four, and the driving devices 7 are respectively located at one end of the four rotating shafts 6. The driving device 7 comprises driving motors, and the synchronous operation of the two filter screens 5 can be realized by adopting four driving motors. The arrangement of the rotating shaft 6 and the filter screen 5 not only promotes the moving stability of the filter screen 5, but also avoids the problem that the rotating shaft 6 can not smoothly drive the filter screen 5 to move integrally due to the fact that the driving force of the driving device 7 is insufficient.

Optionally, the limiting part 8 includes a limiting lock catch, the limiting lock catch is connected to the first frame 3 in a clamping manner, and the other end of the rotating shaft 6 is located in a through hole defined by the limiting lock catch and the first frame 3. When 6 overlengths of pivot in the air conditioner indoor set or including two or more pivot 6 in the air conditioner indoor set, can carry out better spacing fixed with one or more pivot 6 through spacing hasp, make pivot 6 around the central axis axial rotation, avoid appearing leading to the problem of filter screen 5 screens because of the axle center skew.

Optionally, a concave arc section is provided at a corner of the L-like frame of the first frame 3, and a convex arc section is provided at a corner of the L-like frame of the second frame 4, wherein the concave arc section and the convex arc section enclose the accommodating cavity of the first rotating shaft 6. The first rotary shaft 6 is located at a corner between the bottom plate 14 and the side plate 13, and the screen 5 is located between the first rotary shaft 6 and the first frame 3. The cylindrical rotating shaft 6 is inosculated with the arc of the concave arc section of the first frame 3, so that the filter screen 5 can smoothly slide to the vertical track section from the horizontal track section or smoothly slide to the horizontal track section from the vertical track section, and the direction change of the filter screen 5 is smoother. The second rotating shaft 6 is located above the bottom plate 14 to allow the filter screen 5 to move more smoothly. In this way, a powerful driving force can be provided for the movement of the sieve 5, while the problems of jamming and stacking of the sieve 5 can be avoided.

Optionally, the lower edge of the first air opening 11 of the side plate 13 is provided with an inclined elevation structure, and in the side air outlet mode, the inclined elevation structure enables the limit space at the lower part of the first air opening 11 to form a negative pressure region. Thus, the anti-condensation effect can be further improved.
