DETAILED DESCRIPTION

[0019] Embodiments of the present application are described in detail below with reference to examples shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0020] Below, an air conditioner according to an embodiment of the present application is described according to Figure 1

[0021] ​The air conditioner of the embodiment of the present application comprises a shell 1, an evaporator, a first cross-flow fan 6 and a second cross-flow fan 7. The shell 1 is provided with a first air outlet 14, a second air outlet 15 and an air inlet 13, the first air outlet 14 is arranged on the upper side of the shell 1, the second air outlet 15 is arranged at the bottom of the shell 1, and the air inlet 13 is arranged at the front side of the shell 1. The evaporator is installed in the shell 1, and the evaporator divides the inner cavity of the shell 1 into a first chamber 18, a second chamber 19 and a third chamber 110, the first chamber 18 is communicated with the first air outlet 14, the second chamber 19 is communicated with the second air outlet 15, and the third chamber 110 is communicated with the air inlet 13. The first cross-flow fan 6 is installed in the first chamber 18. The second cross-flow fan 7 is installed in the second chamber 19.

[0022] According to the air conditioner of the embodiment of the present application, the first air outlet 14 is arranged on the upper side of the shell 1, thereby effectively solving the problem of rapid sinking of air flow, effectively improving the air outlet distance of the air conditioner and improving the indoor air circulation efficiency. Meanwhile, by installing the first cross-flow fan 6 and the second cross-flow fan 7 in the first chamber 18 and the second chamber 19 respectively, compared with the arrangement of only one fan and one air outlet in the related art, the first cross-flow fan 6 and the second cross-flow fan 7 rotate in opposite directions to jointly suck air to the front side of the shell 1, and air is respectively discharged from the first air outlet 14 and the second air outlet 15, thereby effectively improving the air outlet amount of the air conditioner and also improving the air outlet area, and the user experience is high.

[0023] It should be noted that the up-down, front-back and left-right directions of the shell 1 are consistent with the up-down, front-back and left-right directions after the air conditioner is actually installed. When the air conditioner is running, as shown in the view angle of Figure 1 , the fan wheel of the first cross-flow fan 6 rotates clockwise, and the fan wheel of the second cross-flow fan 7 rotates counterclockwise.

[0024] In some embodiments, as shown in Figure 1 , the diameter D1 of the first cross-flow fan 6 is equal to the diameter D2 of the second cross-flow fan 7, and the central axis of the first cross-flow fan 6 and the central axis of the second cross-flow fan 7 are parallel to each other and coincide on the same vertical plane.

[0025] That is, the first cross-flow fan 6 is located directly above the second cross-flow fan 7, and by arranging the diameters of the first cross-flow fan 6 and the second cross-flow fan 7 to be equal, the installation difficulty of the two in the shell 1 is reduced, and the air outlet amount of the first air outlet 14 and the second air outlet 15 is also avoided to be unstable due to different suction forces of the two, the air outlet amount is larger when the two work in series, and the indoor circulation efficiency is higher.

[0026] In some embodiments, the distance between the central axis of the first cross-flow fan 6 and the central axis of the second cross-flow fan 7 is L1, and the width of the air inlet 13 is L2, wherein 1.5*D1≤L1≤2*D1, and / or L1≤L2≤1.2*L1.

[0027] By setting 1.5*D1≤L1≤2*D1, on the one hand, the distance between the first cross-flow fan 6 and the second cross-flow fan 7 is avoided to be too close to interfere with each other when working in series, affecting the air volume, and on the other hand, the distance between the first cross-flow fan 6 and the second cross-flow fan 7 is avoided to be too far to interfere with the components in the air conditioner, and the structure of the air conditioner is more compact. By setting L1≤L2≤1.2*L1, on the one hand, the air conditioner is ensured to have sufficient air inlet area to further improve the indoor air circulation efficiency, and on the other hand, the width of the air inlet 13 is avoided to be too large to increase the dirt entering the shell 1 and increase the cleaning frequency of the components in the shell 1.

[0028] Specifically, L1 can be 1.5 times, 1.75 times and 2 times the diameter of the first cross-flow fan 6, and L2 can be 1 times, 1.1 times and 1.2 times L1.

[0029] In some embodiments, the minimum distance between the central axis of the first cross-flow fan 6 and the top surface of the shell 1 is H1, and the minimum distance between the central axis of the first cross-flow fan 6 and the rear surface of the shell 1 is L3, wherein 0.75*D1≤H1≤1.5*D1, 0.75*D1≤L3≤1.5*D1.

[0030] By setting L3 to be greater than or equal to 0.75 times D1 and H1 to be greater than or equal to 0.75 times D1, it is effectively avoided that the first cross-flow fan 6 is too close to the first air outlet 14 to increase the risk of accidental touch, and it is effectively ensured that the first cross-flow fan 6 and the first air outlet 14 have a long enough air outlet path, thereby further improving the air outlet distance of the air conditioner. By setting L3 to be less than or equal to 1.5 times D1 and H1 to be less than or equal to 1.5 times D1, it is effectively avoided that the first cross-flow fan 6 is too close to the evaporator to interfere with the heat exchange between the gas and the evaporator.

[0031] Specifically, L3 can be 0.75 times, 1 times, 1.25 times and 1.5 times D1, and H1 can be 0.75 times, 1 times, 1.25 times and 1.5 times D1.

[0032] In some embodiments, as Figure 1As shown, the second air outlet 15 is arranged on the front side of the shell 1 and below the air inlet 13, the inner surface of the second chamber 19 includes an inlet volute lip surface 111, a flow collection surface 112 and an outlet diffuser plane 113 connected in sequence towards the direction close to the second air outlet 15, in the projection plane perpendicular to the length direction of the shell 1, the included angle of the projection of the inlet volute lip surface 111 is W1, the included angle of the projection of the flow collection surface 112 is W2, and the length of the projection of the outlet diffuser plane 113 is L0, wherein 75°≤W1≤85°, 130°≤W2≤150°, 100mm≤L0≤120mm.

[0033] The arrangement makes the air duct line type in the second chamber 19 larger than that in the related art, thereby making the guiding effect of the air flow in the second chamber 19 better, the air outlet volume of the air conditioner at the second air outlet 15 larger, and the air outlet distance longer, thereby making the indoor air circulation efficiency higher.

[0034] Specifically, W1 can be 75°, 80° and 85°, W2 can be 130°, 140° and 150°, and L0 can be 100mm, 110mm and 120mm.

[0035] In some embodiments, the evaporator includes first to fourth evaporators 2, 3, 4 and 5 arranged in sequence from top to bottom, the first and second evaporators 2 and 3 separate the first and third chambers 18 and 110, the first and second evaporators 2 and 3 surround the first V-shaped groove 16 towards the first chamber 18, and the third and fourth evaporators 4 and 5 separate the second and third chambers 19 and 110, and the third and fourth evaporators 4 and 5 surround the second V-shaped groove 17 towards the second chamber 19.

[0036] By arranging the first and second evaporators 2 and 3 at an angle and the third and fourth evaporators 4 and 5 at an angle, the heat exchange area of the evaporator is effectively increased, the cooling or heating effect of the air flow in the third chamber 110 when passing through the evaporator into the first and second chambers 18 and 19 is better, and thus the refrigeration and heating efficiency of the air conditioner is higher.

[0037] Specifically, the first to fourth evaporators 2 to 5 are all plate-type evaporators, and the first to fourth evaporators 2 to 5 are connected in sequence from top to bottom, and the lower end of the second evaporator 3 and the upper end of the third evaporator 4 both abut against the inner surface of the shell 1.

[0038] In some embodiments, the angle between the two opposite sides in the first V-shaped groove 16 along the height direction of the shell 1 is N1, and the angle between the two opposite sides in the second V-shaped groove 17 along the height direction of the shell 1 is N2, wherein 45°≤N1≤100°, 45°≤N2≤100°.

[0039] The arrangement not only ensures that the first to fourth evaporators 2-5 form a larger heat exchange area, so that the air conditioner has higher refrigeration and heating efficiency, but also avoids the connection of the first and second evaporators 2 and 3 and the connection of the third and fourth evaporators 4 and 5 from excessively occupying the third chamber 110 to increase the resistance of the airflow passing through the first to fourth evaporators 2-5, effectively ensuring the energy efficiency ratio of the air conditioner.

[0040] Specifically, N1 can be 45°, 60°, 75°, 90°, and 100°, and N2 can be 45°, 60°, 75°, 90°, and 100°.

[0041] In some embodiments, the minimum distance between the central axis of the second evaporator 3 and the first cross-flow fan 6 in the width direction of the shell 1 is L4, and the minimum distance between the central axis of the third evaporator 4 and the second cross-flow fan 7 in the width direction of the shell 1 is L5, wherein 22mm≤L4≤35mm and 40mm≤L5≤60mm.

[0042] The arrangement not only ensures that the first to fourth evaporators 2-5 form a larger heat exchange area, so that the air conditioner has higher refrigeration and heating efficiency, but also avoids the connection of the first and second evaporators 2 and 3 and the connection of the third and fourth evaporators 4 and 5 from excessively occupying the third chamber 110 to increase the resistance of the airflow passing through the first to fourth evaporators 2-5, effectively ensuring the energy efficiency ratio of the air conditioner.

[0043] Specifically, the minimum distance between the central axis of the first evaporator 2 and the first cross-flow fan 6 in the width direction of the shell 1 is greater than L4, the minimum distance between the central axis of the fourth evaporator 5 and the second cross-flow fan 7 in the width direction of the shell 1 is greater than L5, and L4 can be 22mm, 30mm, and 35mm. L5 can be 40mm, 50mm, and 60mm.

[0044] In some embodiments, the air inlet 13 is provided with an air inlet grille 8, the minimum distance between one of the first and second evaporators 2 and 3 and the air inlet grille 8 in the width direction of the shell 1 is L6, the minimum distance between the other of the first and second evaporators 2 and 3 and the air inlet grille 8 in the width direction of the shell 1 is L7, the minimum distance between one of the third and fourth evaporators 4 and 5 and the air inlet grille 8 in the width direction of the shell 1 is L8, and the minimum distance between the other of the third and fourth evaporators 4 and 5 and the air inlet grille 8 in the width direction of the shell 1 is L9, wherein 33mm≤L6≤39mm, 28mm≤L7≤33mm, 13mm≤L8≤20mm, and 10mm≤L9≤33mm.

[0045] The arrangement avoids the first evaporator 2 to the fourth evaporator 5 being too close to the air inlet grille 8 to increase the risk of accidental touch, and makes the air conditioner internal structure compact while increasing the heat exchange area of the first evaporator 2 to the fourth evaporator 5.

[0046] Specifically, the front panel 12 and the air inlet grille 8 are both angled with the vertical direction, and the lower end of both is inclined rearward relative to the upper end. L6 is generally greater than L7, and L8 is generally greater than L9. L6 can be 33mm, 36mm and 39mm, L7 can be 28mm, 30mm and 33mm. L8 can be 13mm, 17mm and 20mm, and L9 can be 10mm, 15mm, 19mm and 33mm.

[0047] In some embodiments, the shell 1 includes a base 11 and a front panel 12, the base 11 is provided with a first water pan 9 and a second water pan 10, the first water pan 9 is located below the lower end of the second evaporator 3, and the second water pan 10 is located below the lower end of the fourth evaporator 5.

[0048] The first water pan 9 can effectively collect the condensed water from the first evaporator 2 and the second evaporator 3, and the second water pan 10 can effectively collect the condensed water from the third evaporator 4 and the fourth evaporator 5, thereby effectively reducing the probability of the condensed water falling outside the air conditioner, and improving the user experience.
