In other embodiments, the third transverse frame portion 21 and the second sliding rod may be cylindrical in shape.

[0041] In some embodiments, the third transverse frame portion 21 cooperates with the first sliding groove 111, so that the third transverse frame portion can slide with the first transverse frame portion 11, thereby realizing flexible adjustment of the return air frame length. Similarly, the second sliding rod cooperates with the second sliding groove, so that the fourth transverse frame portion 22 can slide with the second transverse frame portion 12, thereby realizing flexible adjustment of the return air frame length.

At least one of the first connecting portion 131 and the second connecting portion 132 is provided with a second locking member 40. The second locking member 40 is configured to fix the first connecting portion 131 and the second connecting portion 132 when the first connecting portion 131 slides to a second preset position along a second direction; the second direction is perpendicular to the first direction.

[0046] In one example, the first connecting portion 131 slides along the second direction, so that the first longitudinal frame portion 13 is easier to align and fix during installation. In some embodiments, the second locking member 40 can be a screw, a bolt, a latch, etc., for fixing the first connecting portion 131 and the second connecting portion 132 when the first connecting portion 131 slides to the second preset position.

[0047] In some embodiments, Figure 7 This is a schematic diagram of the third connecting portion, the fourth connecting portion and the third locking member provided in the embodiment of the present application.

[0049] Figure 8 This is a schematic diagram of the second return air frame provided in the embodiment of the present application. Figures 1 to 8 In some embodiments, the first longitudinal frame portion 13 further includes a fifth connection portion 133 and a sixth connection portion 134. The fifth connection portion 133 and the sixth connection portion 134 are slidably matched, and at least one of the fifth connection portion 133 and the sixth connection portion 134 is provided with a second locking member 40, and the second locking member 40 is configured to fix the fifth connection portion 133 and the sixth connection portion 134 when the fifth connection portion 133 slides to the second preset position. Among them, the first connection portion 131 and the fifth connection portion 133 are arranged opposite to each other, and the second connection portion 132 and the sixth connection portion 134 are arranged opposite to each other. By arranging the first connection portion 131 and the fifth connection portion 133 in parallel, and the second connection portion 132 and the sixth connection portion 134 in parallel, a quadrilateral structure can be formed. An opening for placing the filter net is formed in the middle part of the quadrilateral structure, which can ensure the smooth installation of the filter net.

[0050] In some embodiments, the second longitudinal frame portion 23 further includes a seventh connection portion 233 and an eighth connection portion 234. The seventh connection portion 233 and the eighth connection portion 234 are slidably matched, and at least one of the seventh connection portion 233 and the eighth connection portion 234 is provided with a third locking member 50, and the third locking member 50 is configured to fix the seventh connection portion 233 and the eighth connection portion 234 when the seventh connection portion 233 slides to the third preset position.

By arranging the third connection portion 231 and the seventh connection portion 233 in parallel, and the fourth connection portion 232 and the eighth connection portion 234 in parallel, a quadrilateral structure can be formed. The middle part of this quadrilateral structure forms an opening for taking out the filter net, which can ensure the smooth installation of the filter net.

[0051] In some embodiments, see Figures 1 to 8 , the second locking member 40 includes a first bolt 41, and the third locking member 50 includes a second bolt 51. In some embodiments, the first bolt 41 and the second bolt 51 both have the function of preventing loosening and stabilizing, so they can effectively prevent the connection parts from loosening and vibrating during long-term use. For example, the first connecting portion 131 has a plurality of first through holes 1311 at equal intervals, and the second connecting portion 132 has a plurality of second through holes 1321 at equal intervals. The first bolt 41 firmly connects any first through hole 1311 with any second through hole 1321, ensuring the stability of the first connecting portion 131 and the second connecting portion 132, thereby achieving flexible adjustment of the width of the return air frame. Similarly, the third connecting part 231 has a plurality of equally spaced third through holes 2311, and the fourth connecting part 232 has a plurality of equally spaced fourth through holes 2321, and the second bolt 51 firmly connects any third through hole 2311 with any fourth through hole 2321, thereby ensuring the stability of the third connecting part 231 and the fourth connecting part 232, thereby realizing flexible adjustment of the width of the return air frame.

[0052] In some embodiments, see Figures 1 to 8 The width of the first transverse frame portion 11 is less than or equal to the width of the third transverse frame portion, so that the first transverse frame portion 11 and the third transverse frame portion can be slidably matched.

[0053] In some embodiments, the width of the second transverse frame portion 12 is less than or equal to the width of the fourth transverse frame portion 22 , so that the second transverse frame portion 12 and the fourth transverse frame portion 22 can be slidably matched.

[0054] Furthermore, in order to better implement the return air frame in the embodiment of the present application, on the basis of the return air frame, the present application also provides an air conditioner, wherein the refrigerator includes the above-mentioned return air frame. In the air conditioner, since the first transverse frame portion of the first frame member slides with the third transverse frame portion of the second frame member, and the second transverse frame portion of the first frame member slides with the fourth transverse frame portion of the second frame member, the relative position adjustment of the first frame member and the second frame member along the first direction can be achieved, and when the second frame member is slid along the first direction to the first preset position, the first frame member and the second frame member are fixedly connected by the first locking member so that the overall frame of the return air frame is fixed, and finally the purpose of adjustable size of the return air frame is achieved, avoiding the current phenomenon that the return air frame is fixed in size and cannot be adapted to air conditioners of different models.

[0055] In some embodiments, the air conditioner includes an air conditioning body, the first frame member has a first fixing portion, the second frame member has a second fixing portion, and the first fixing portion and the second fixing portion are fixedly connected to the air conditioning body.

[0056] Specifically, the fourth locking member may be a self-tapping screw. The first fixing portion has a plurality of fifth through holes at equal intervals, the second fixing portion has a plurality of sixth through holes at equal intervals, and the edge of the air conditioning box has a plurality of seventh through holes at equal intervals. The self-tapping screw firmly connects the fifth through hole and the seventh through hole together, ensuring that the air conditioning box and the first frame member are fixed and remain stable. The self-tapping screw also firmly connects the sixth through hole and the seventh through hole together, ensuring that the air conditioning box and the second frame member are fixed and remain stable.
