In the present embodiment, if the front panel 21 is provided in a flat plate shape, after installation, the gap area between the front panel 21 and other components (such as the air guide plate 30) tends to be unsightly due to the lack of a transition structure, and dust is easily introduced into the machine body from such a gap without a transition structure, which affects the performance of the machine.

In some embodiments of the present utility model, two bending plates 214 are respectively disposed on two sides of a middle plate 213 of the front panel 21, the bending plates 214 are disposed at an obtuse angle with respect to the middle plate and have an included angle direction facing the inner side of the front panel, and the bending plates can be used as a transition structure of the matching gap between the front panel 21 and the air deflector 30.

Therefore, when the air deflector 30 closes the heat exchange air outlet 17, the bending plate 214 of the front panel 21 is used as a transition structure at the matching gap between the air deflector 30 and the front panel 21, so that the appearance of the matching gap is optimized, and part of dust can be prevented from entering the air conditioner body.

After the front panel 21 is mounted on the panel seat 10, if the inner side surface of the bending plate 214 contacts with the substrate 13, abnormal noise is generated between the inner side surface and the substrate 13 due to mutual friction caused by different degrees of expansion caused by heat and contraction caused by cold during the use of the panel seat 10 and the front panel 21.

Accordingly, in the present embodiment, the inner side surface of the bending plate 214 is provided so as not to contact the base plate 13.

However, since the front panel 21 is a large panel member, such a large panel member is liable to be deformed in the left-right direction after production, for example, a depression of a partial region is generated on the bending plate 214, and thereby the fit clearance between the front panel 21 and the air deflector 30 is caused to be uneven.

In order to improve the deformation problem of the large panel member in the left-right direction, a plurality of protrusions 14 are further provided on the base plate 13, and a third gap is formed between the bending plate 214 and the base plate 13 along the left-right direction, and the protrusions 14 are located between the third gap. The dimension of the protrusion 14 in the normal direction along the substrate 13 is larger than the dimension of the gap between the inner side surface of the bending plate 214 and the substrate 13 of the panel seat 10, i.e., the protrusion 14 abuts against the inner side surface of the bending plate 214.

Therefore, the protrusion 14 supports the bending plate 214 of the front panel 21, thereby preventing the deformation of the front panel 10 in the left-right direction and making the fitting gap between the front panel 21 and the air deflector 30 uniform.

In addition, the contact area of the protrusion 14 is smaller than that of the bending plate 214 in full contact with the substrate 13, so that abnormal noise phenomenon can be effectively prevented.

In the present embodiment, the projections 14 are formed in a prismatic shape on the substrate 13, and if the contact area between the front panel 21 and the panel seat 10 is further reduced, the projections 14 may be also provided in a spherical shape.
