DETAILED DESCRIPTION

[0021] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0022] The air conditioner according to an embodiment of the present application is described below in conjunction with Figure 1

[0023] The air conditioner according to an embodiment of the present application is described below in conjunction with

[0024] ​According to the air conditioner provided by the embodiment of the present application, the upper air outlet 13 is arranged on the top surface of the shell 1, which effectively solves the problem of the rapid sinking of the air flow, and further effectively improves the air outlet distance of the air conditioner. In addition, the top surface of the shell 1 is arranged to extend downward from back to front, so that a structure similar to an expanding structure is formed between the top surface of the shell 1 and the roof of the wall, which further avoids the air flow directly blowing against the roof of the wall to cause air volume loss, so that the air volume of the air conditioner is larger, the air outlet distance is longer, and the indoor air circulation efficiency is higher.

[0025] 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 of the air conditioner after actual installation.

[0026] In some embodiments, as shown in Figure 1 the top surface is at an angle M1 with the height direction of the shell 1, the distance between the front edge and the rear edge of the top surface is L1, the distance between the front edge and the rear edge of the upper air outlet 13 is L2, 0.42≤L1 / L2≤0.6, and / or 65°≤M1≤85°.

[0027] By setting 65°≤M1≤85°, it is ensured that the top surface of the shell 1 has sufficient slope to form a large enough expanding channel between the top surface and the roof of the wall, further ensuring the air volume and air outlet distance of the air conditioner, and effectively avoiding that the inclination angle of the top surface of the shell 1 is too large to affect the installation of the components in the shell 1 and the appearance of the air conditioner. By setting 0.42≤L1 / L2≤0.6, it is ensured that the upper air outlet 13 has a large enough air outlet area, and the air flow has a large enough air outlet speed, thereby having a longer air outlet distance.

[0028] Specifically, L1 / L2 can be 0.42, 0.5 and 0.6. M1 can be 65°, 70°, 75° and 85°.

[0029] In some embodiments, as shown in Figure 1 on the projection plane perpendicular to the length direction of the shell 1, the projection of the evaporator 2 is a strip shape, and the extension direction of the projection of the evaporator 2 is at an angle N1 with the width direction of the shell 1, wherein 15°≤N1≤60°.

[0030] That is, the evaporator 2 is a inclined plate structure at an angle with the horizontal direction, so that when the air flow passes through the evaporator 2, the evaporator 2 can guide and comb the passing air flow, so that the air flow can flow more uniformly through the surface of the evaporator 2, ensuring that all parts of the evaporator 2 can fully participate in heat exchange, avoiding local uneven heat exchange to affect the heat exchange efficiency of the evaporator 2. In addition, the inclined evaporator 2 also facilitates the condensate water to flow along the inclined surface to the water pan 4, effectively preventing water accumulation in the evaporator 2, reducing the hidden danger of affecting air conditioner use and indoor air quality due to water accumulation breeding bacteria, mold and the like.

[0031] Specifically, the angle N1 between the evaporator 2 and the horizontal direction can be 15°, 30°, 45°, and 60°.

[0032] In some embodiments, the front air inlet 14 is provided with an air inlet grille 5, the air flow direction in the air inlet grille 5 is at an angle M2 with the evaporator 2, and the air flow direction in the air inlet grille 5 is at an angle M3 with the height direction of the shell 1, wherein 45°≤M2≤70°, and / or 5°≤M3≤18°.

[0033] In this way, the air flow entering the second chamber 16 can pass through each part of the evaporator 2 more uniformly, the heat exchange process between the air flow and the evaporator 2 is relatively stable, and the cooling and heating functions of the air conditioner can be continuously and stably realized. At the same time, the orientation of the air inlet holes in the air inlet grille 5 is closer to the vertical direction, dust from the outside is less likely to enter the second chamber 16 through the air inlet grille 5, and users are less likely to observe the components in the shell 1 through the air inlet grille 5, so the appearance of the air conditioner is high in aesthetic degree.

[0034] Specifically, M2 can be 45°, 60°, and 70°, and M3 can be 5°, 12°, and 18°.

[0035] In some embodiments, the front end of the evaporator 2 is higher than the rear end of the evaporator 2, and the shell 1 is provided with a water pan 4, the water pan 4 is located below the lower edge of the evaporator 2, and the water pan 4 is located behind the air inlet grille 5.

[0036] At this time, the water pan 4 and the air inlet grille 5 are arranged in the front-rear direction, and the air flow from the air inlet grille 5 blows to the evaporator 2 without being blocked by the water pan 4 to cause wind volume consumption, effectively reducing the load of the fan, and the energy efficiency ratio of the air conditioner is higher.

[0037] In some embodiments, as shown in Figure 1 The shell 1 includes a base 11 and a front panel 12 connected to each other, the front panel 12 is located in front of the base 11, and the inner surface of the second chamber 16 includes a first side surface 121 formed on the front panel 12, the first side surface 121 is at an angle M4 with the evaporator 2, and the minimum distance between the first side surface 121 and the evaporator 2 in the width direction of the base 11 is D, wherein 20°≤M4≤55°, and / or 15mm≤D≤50mm.

[0038] By setting 20°≤M4≤55°, the inner surface of the front panel 12 can better guide the incoming air flow to the evaporator 2, effectively avoiding the incoming air flow from staying in the upper right area of the evaporator 2, and effectively ensuring the refrigeration and heating efficiency of the air conditioner. By setting 15mm≤D≤50mm, it not only avoids the evaporator 2 and the front panel 12 being too close in the front-back direction to increase the probability of the incoming air flow staying in the upper right area of the evaporator 2, but also avoids the evaporator 2 and the front panel 12 being too far apart in the front-back direction to cause the heat exchange area of the evaporator 2 to be small, which affects the refrigeration and heating efficiency of the air conditioner.

[0039] Specifically, the angle M4 between the first side surface 121 and the front side surface of the evaporator 2 can be 20°, 30°, 40°, and 55°, and the minimum distance D in the front-back direction between the first side surface 121 and the front upper edge of the evaporator 2 can be 15mm, 30mm, 45mm, and 50mm.

[0040] In some embodiments, as shown in Figure 1 The shell 1 includes a base 11 and a front panel 12 connected to each other, the front panel 12 is located in front of the base 11, and the inner surface of the first chamber 15 includes a second side surface 111 formed on the base 11, the second side surface 111 is at an angle M5 with the evaporator 2, wherein 15°≤M5≤60°.

[0041] The second side surface 111 is adjacent to the lower end area of the evaporator 2, and the incoming air flow passing through the evaporator 2 can better flow to the fan under the guidance of the second side surface 111, effectively preventing air flow disturbance in the first chamber 15 and causing air volume loss, thereby further improving the air volume of the air conditioner.

[0042] Specifically, the angle M5 between the second side surface 111 and the rear side surface of the evaporator 2 can be 15°, 30°, 45°, and 60°.

[0043] In some embodiments, the first chamber 15 includes an air outlet air duct extending to the upper air outlet 13, the inner surface of the air outlet air duct includes a third side surface 151 and a fourth side surface 152 opposite along the width direction of the shell 1, the third side surface 151 is located behind the fourth side surface 152, and the third side surface 151 and the fourth side surface 152 both extend forwardly and upwardly towards the upper air outlet 13.

[0044] That is, the air outlet air duct extends upwardly and forwardly towards the upper air outlet 13, thereby causing the outlet air flow to blow upwardly and forwardly into the room, effectively avoiding the outlet air flow being blocked by the wall surface and the wall top to cause air volume loss, and effectively ensuring the air conditioner to have a longer air outlet distance and a high indoor air circulation efficiency.

[0045] In some embodiments, the third side surface 151 is at an angle M6 to the top surface, and the fourth side surface 152 is at an angle M7 to the top surface, wherein 30°≤M6≤80°, and / or 100°≤M7≤150°.

[0046] This arrangement, on the one hand, increases the air outlet angle of the air outlet air duct, and on the other hand, avoids the width of the air outlet air duct being too large to cause the air outlet wind speed to be small, thereby affecting the air outlet distance, and effectively improves the indoor air circulation efficiency. Moreover, by arranging the inclination angle of the third side surface 151 at the upper air outlet 13 to be smaller than the inclination angle of the fourth side surface 152 at the upper air outlet 13, the air outlet air duct is ensured to have a trumpet-shaped flared structure, thereby effectively increasing the air outlet angle and air outlet area of the air conditioner, and providing a better user experience.

[0047] Specifically, M6 can be 30°, 55°, and 80°, and M7 can be 100°, 125°, and 150°. When the third side surface 151 and the fourth side surface 152 are arc surfaces, M6 is the angle between the top surface and a plane tangent to the third side surface 151 at the rear edge of the upper air outlet 13, and M7 is the angle between the top surface and a plane tangent to the fourth side surface 152 at the front edge of the upper air outlet 13.

[0048] In some embodiments, the inner surface of the first chamber 15 further comprises a flow collecting surface 112, the upper end of the flow collecting surface 112 is connected to the lower end of the third side surface 151, and the minimum distance S between the flow collecting surface 112 and the rear side surface of the shell 1 in the width direction of the shell 1 is 8mm≤S≤18mm.

[0049] This arrangement, on the one hand, ensures that the base 11 has sufficient structural strength and support strength, so that the air conditioner has a longer service life, and on the other hand, avoids the rear wall of the base 11 excessively occupying the inner cavity of the shell 1, thereby affecting the flow collecting effect of the gas, and the air outlet effect of the air conditioner is better.

[0050] Specifically, S can be 8mm, 12mm, 14mm, and 18mm.

[0051] In some embodiments, the third side surface 151 is an arc surface with a central angle of M8, the fourth side surface 152 comprises a first plane 1521 and a first arc surface 1522 connected in sequence from the position of the volute tongue to the direction close to the air outlet, the first plane 1521 is at an angle M9 to the height direction of the shell 1, and the first arc surface 1522 has a central angle of M10, wherein 50°≤M8≤75°, 40°≤M9≤80°, and 70°≤M10≤110°.

[0052] This arrangement, on the one hand, increases the air outlet angle of the air outlet air duct, and on the other hand, avoids the width of the air outlet air duct being too large to cause the air outlet wind speed to be small, thereby affecting the air outlet distance, and effectively improves the indoor air circulation efficiency.

[0053] Specifically, the third side surface 151 is smoothly connected with the current collecting surface 112, the center of the third side surface 151 coincides with the center of the volute tongue, and the center of the first arc surface 1522 is located at the intersection of the center line of the air outlet air duct and the top surface of the shell 1. M8 can be 50°, 55°, 60°, 65°, 70° and 75°, M9 can be 40°, 50°, 60°, 70° and 80°, and M10 can be 70°, 80°, 90°, 100° and 110°.
