An air conditioning indoor unit, see fig. 1, 2, 4, 5, 7, 9, 10, comprising:

the panel 1 arranged on the outer surface of the air-conditioning indoor unit adopts an extrusion type processing mode for the panel 1 so as to reduce the production cost of the panel 1 and reduce the thickness of the panel 1,

the panel 1 is cylindrical and comprises a rear panel 11, and an air inlet 12 is arranged on the rear panel 11; a left panel 13 fastened to the left end of the rear panel 11; the right panel 14 is clamped at the right end of the rear panel 11, the right panel 14 and the left panel 13 have the same size, and an air outlet 15 is formed between the left panel 13 and the right panel 14; the shapes of the plate surfaces of the rear panel 11, the left panel 13 and the right panel 14 are circular arc,

the supporting rods 2 are sheet metal parts, and the supporting rods 2 are vertically connected to the inner walls of the rear panel 11, the left panel 13 and the right panel 14 respectively, and are specifically connected to the middle of the rear panel 11, the position of the left panel 13 close to the air outlet 15 and the position of the right panel 14 close to the air outlet 15 so as to be used as supports of the panel 1;

the air duct component 3 is connected with the supporting rod 2;

in order to increase the areas of the air inlet 12 and the air outlet 15 and improve the heat exchange efficiency, the ratio L1 between the arc length L1 of the overlapped surface of the left panel 13 or the right panel 14 clamped with the rear panel 11 and the width L2 of the air inlet 12 is: the range of L2 is (1: 10) - (1: 6), the overlapping surface of the left panel 13 or the right panel 14 and the rear panel 11 in clamping connection directly affects the limit width of the air inlet 12, and when the overlapping surface of the left panel 13 or the right panel 14 and the rear panel 11 in clamping connection increases, the limit width of the air inlet 12 decreases; on the contrary, the limit width of the air inlet 12 will be increased,

when L1: l2 is 1: when 10, the width of the air inlet 12 is increased, but the area of the overlapping surface is reduced, so that the connection strength between the left panel 13 or the right panel 14 and the rear panel 11 is weakened;

when L1: l2 is 1: 6, although the area of the overlapping surface is increased, the width of the air outlet 15 is reduced, so that the air inlet volume is reduced, and the heat exchange efficiency is influenced;

only when L1: l2 is 1: when the air inlet 12 is formed in the rear panel 11, the air inlet 13 or the right panel 14 is formed in the rear panel, and the air inlet 12 is formed in the rear panel;

ratio L3 of the arc length of the left panel 13 or the arc length L3 of the right panel 14 to the transverse arc length L4 of the rear panel 11: the ratio range of L4 is (1: 3) to (2: 1),

the relation of the ratio of the arc length L3 of the left panel 13 or the arc length L3 of the right panel 14 to the transverse arc length L4 of the rear panel 11 influences the connection strength between the left panel 13 or the right panel 14 and the rear panel 11 when the air conditioner size is fixed and the air outlet condition is satisfied, i.e. the air conditioner size is not changed and the air outlet 15 is a fixed value,

when the arc length of the arc surface of the left panel 13 or the arc length L3 of the arc surface of the right panel 14 is increased, the arc length L4 of the arc surface of the back panel 11 is inevitably decreased, the arc length L4 of the arc surface of the back panel 11 is decreased, so that the connection strength between the left panel 13 or the right panel 14 and the back panel 11 is weakened, and the air inlet 12 is correspondingly decreased,

conversely, when the arc length of the arc surface of the left panel 13 or the arc length L3 of the arc surface of the right panel 14 is decreased, the arc length L4 of the arc surface of the back panel 11 is increased, the arc length L4 of the arc surface of the back panel 11 is increased, and the connection strength between the left panel 13 or the right panel 14 and the back panel 11 is also weakened;

when L3: l4 is 1: at the time of 3, the arc length L3 of the left panel 13 or the right panel 14 is one third of the transverse arc length L4 of the rear panel 11, and since the panel 1 is an extrusion type panel, the thickness of the panel 1 is relatively thin, which inevitably weakens the connection strength between the rear panel 11 and the left panel 13 or the right panel 14, and the connection stability is relatively poor, so that the panel 1 is easily deformed as a whole.

When L3: l4 is 2: at 1, the arc length L3 of the left panel 13 or the right panel 14 is 2 times of the transverse arc length L4 of the rear panel 11, and there is also a problem that the connection strength between the rear panel 11 and the left panel 13 or the right panel 14 is weakened, which directly results in poor connection stability and deformation of the panel 1.

Only when L3: l4 is 1: 2, namely the arc length of the left panel 13 or the arc length L3 of the right panel 14 is half of the transverse arc length L4 of the rear panel 11, the support rod 2 is supported in the middle of the rear panel 11, and the connecting position of the left panel 13 or the right panel 14 and the rear panel 11 and the position of the support rod 2 form a support point, at this time, the connecting strength between the rear panel 11 and the left panel 13 or the right panel 14 is optimal, the continuous temperature performance is good, and the panel 1 is not easy to deform.

Referring to fig. 2 and 3, a display panel 16 is connected between the upper ends of the left panel 13 and the right panel 14, a front panel 17 is connected between the lower ends of the left panel 13 and the right panel 14, the display panel 16 is located above the front panel 17, an air outlet 15 is formed between the left panel 13, the right panel 14, the display panel 16 and the front panel 17, and the display module 4 is connected to the inner wall of the display panel 16.
